PreppComm ɑ End Fed NO TUNE 80/40/20 Antenna Unlike the PreppComm NO TUNE 40/20 antenna, which is a complete system for rapid deploy and repacking, this end fed is designed for permanent installation. However, it is also possible to use in a temporary setup by providing the needed additional components (not included). The antenna can be used without a tuner with a reasonable SWR, or perfect SWR if you add an antenna tuner (not included). The antenna is approximately 60 feet long, and supports 250W PEP SSB, 125W CW, and 25W digital. The antenna can achieve good SWR at 80M, even though the antenna is approximately the same length as our NO TUNE 40/20 antenna, which only operates on 40 and 20 meters. This is due to a different transformer design. The SWR performance is actually better at 80M (SWR = 2.1) than at 40M (SWR = 2.7), but gets better at 20M (SWR = 2.2). All of these SWR’s will be sufficiently low for the MMX series to operate safely. If a tuner is used, then the SWR can be adjusted very close to 1:1. The antenna comes with two terminals to attach the wires, and an eye bolt on the other side of the main transformer, along with the RF connector. The antenna wire attaches to the two terminals, and ends with insulators at the other end. The antenna is rigged using the eye bolt and the insulators via non-conductive support cables (not included). Deploy the antenna in a sloper configuration (low near the transceiver, high at the other end, perhaps via a tree and support line) or horizontal configuration at least 6’ off the ground. A sloper configuration will provide both NVIS and DX functionality, while horizontal near the ground will primarily provide NVIS operation. For DX focus, install in a horizontal configuration as high as possible. Keep at least 6’ from trees, buildings and foliage for best results. Use longer support lines to the included insulators and the eye bold on the main transformer unit to keep antenna free from obstacles..The feed line attaches via a PL-239 plug on the support end of the transformer. Antenna is shipped separately from a separate location. The shipping cost is included in the price.

Included 1 – 25 inch mast in two pieces that couple together, 3 – 22-inch tripod leges in two pieces that couple together, 1 – Tuning box with 3 built-in female tripod leg inserts and 1 female 5/8 11 tripod mount, 1 – Fine tuning fulcrum rod, 1 – BNC Female to UHF PL259 Male adapter, 1 - BNC Female to SMA male to mate with the SMA type cable connectors 1 – Outer LMR400 heavy duty coax loop, 1 – Inner shielded faraday loop with a 9' feed line and BNC connector, and 1 – PreppComm zippered Field Bag. This antenna is truly a breakthrough - the size and weight for portability is truly a step forward from portable magnetic loops of the past, and the built-in tuner uses a unique; and easy to use tuning system. Construction is top quality to ensure long life in both wet and dry climates. The antenna can be operated indoors or outdoors, however better results will be attained outdoors. For best results indoors, operate near a window that faces the direction you wish to transmit toward. Focus is on the rim, not through the center, as most suppose! The antenna is 20" in diameter. Materials Used Isn’t it obvious why the price is high when you see the following materials used in the construction of the PREPPCOMM α MagLoop antenna? Gold, Solder, Ceramic, Aluminum, Stainless steel, Marine shrink tubing, Times Microwave LMR400, and Carbon Fiber infused polymers. This Magnetic Loop is a great companion to your MMX, DMX-40, or MMX Nomad because it is just as fast, if not faster, to set up and take down as the NO TUNE End Fed antenna, is more compact and easy to aim, not fixed in direction like the End Fed, and can be even operated indoors. However, you do lose some signal strength from the smaller size compared to the long wire End Fed antenna. Assembly 1. Assemble the mast and insert into the tuning unit (photo 3) 2. Uncoil the LMR400 outer loop, and carefully determine the center. Attach the center to the top of the mast by pressing into the slot, and form the LMR400 into a loop. 3. Plug the PL239 connectors into the tuning unit, and tighten. Hold the LMR400 in position so the connector can be tightened all the way in. 4. Now you should have something looking like photo 4. 5. Place the inner loop top into the slot at the top of the mast, centered. 6. Attach the small inner loop via the two clips to the outer loop, as shown in photo 5. 7. Put the three legs together, and push the top end into the angled holes provided in the underside of the tuning unit. Note: the two pieces are held together by the weight of the antenna above, so during assembly you have to make sure you provide support so they don't separate. 8. Now you have a complete Magnetic Loop, as shown in photo 6. Connect to the transceiver. Tuning the Antenna For UHF/VHF, tuning is by adjusting the spacing on the clips holding the inner loop to the outer loop. For HF, the tuning rod (see photo 2) is used. Slowly turn the rod, looking for the place where the background noise in your receiver gets much louder. Note this position of the rod: this position is for the band you are using, so you can move to this position quickly the next time. Now, carefully adjust for maximum noise in the receiver. If you have a tuning mode, or an SWR meter, after you have found the maximum background noise point, you can then turn on the transmitter in a low power mode, and make finer adjustments with the tuning rod via lower SWR. Specifications, prices, and descriptions are subject to change without notice.

Low Loss 8m (26 ¼ foot) Antenna Male to Female SMA Coax Cable This LMR-100 low loss coaxial cable is the big brother to the 3m cable that is a part of the Professional Station GO Bag outfit for a complete radio station in a portable 8 pound bag.  It connects from the DMX-40 or MMX Morse Code Transceiver output antenna connector to the 40/20M No-Tune End-Fed Antenna, also included in the GO Bag, and manufactured by PreppComm for low SWR across the entire 40/20M band. Replacement or Extend Length This high power coax cable can be used to replace a damaged or missing cable from a GO Bag system, or can also be used to extend the original cable length, if desired. Up to 2 cables can be daisy-chained, for a total length of over 52 feet with slightly increased loss of power to the antenna. Or, you can add this to your 3m cable and get about 36' of total length. Lengths longer than 40 feet require LMR-200 or LMR-400 to reduce power loss during transmit.

Highest Quality Strain Relief Plus Connector Adaptor If you are using an existing antenna system, before you do, make sure the SWR is below 2:1 before connecting it to the MMX or DMX-40. This adaptor cable is designed to connect between the rear SMA female antenna connector on the MMX or DMX-40 and the standard antenna PL-239 plug. It also serves a second purpose, which is to reduce mechanical stress on both the PL-239 and its attachment to its likely stiff RF cable, and the very light and portable MMX with its PC-mounted SMA female connector. These cables are extremely well built, with multiple layers of sleeving to reduce the stress on the solder joints, in order to provide long life. At the SMA connector end, note the two-lawyer cable relief design. At the SO-239 end, a 3-layer cable relief design is used to compensate for the larger connector. In addition, a clear cap is provided to protect the internal surfaces of the connector when not in use. Keep an Extra on Hand! We suggest, at this low price, you consider purchasing two adaptors, as all of the stress caused by the heavy duty PL-239 connector and coax will be handled by this adaptor, and thus, depending on your use case, it is the most likely to fail first. Don't be without when that happens after a few years - have a spare handy!

NO TUNE 40/20 Meter End-Fed Antenna with Unique Setup Kit Overview This is a very unique antenna designed initially for the Professional Ham Station GO Bag, and now extended to multi-band for MMX. It operates on both 40 meters and 20 meters, and does not need to be tuned. This is accomplished via a unique transformer in the antenna matchbox, but requires a counterpoise to operate correctly. The counterpoise wire is of course included as part of the antenna, and complete setup instructions for a sloper and inverted V configurations are included. The antenna is designed for temporary setup using the included setup kit, and is not intended for a permanent setup. It is a truly stealthy, lightweight, portable antenna.  However, we include in the setup kit tags (not shown in the images) and flags to use when stealth is not required, to prevent accidental damage to the antenna or persons running into the virtually invisible wire and paracord. And the antenna kit is packaged in a very handsome waterproof 14 oz heavy duty waterproof canvas zipper pouch, to keep everything together and for easy carrying and storage. Canvas color may vary. Note that each component is within its own ziplock bag inside the canvas bag, to keep things neat and organized. The Antenna The antenna itself is designed around information documented by AA5TB in his extensive review of end fed antennas with and without counterpoise wires. As far as we know, our design is unique, and utilizes a fascinating point on the curve where the antenna becomes nearly pure resistive as a load, and thus, is radiating nearly all of the applied power into the atmosphere. It operates well in several configurations, but the easiest to set up are the two mentioned above, sloper and inverted-v. Extensive instructions for setup and takedown are included with the kit in a plastic document folder, and the PDF file is here if you want to print it in another format. The antenna consists of two PolyStealth AWG 26 wires - one, the antenna main wire, and the other, the required counterpoise. The PolyStealth wire is copper-coated steal multiple strand wire, coated with a black anti-UV and anti-reflective coating.  It is extremely difficult to see even when you know where it is! Thus, the included tags and flags. The Setup Kit This is a totally unique kit. The goal was to provide a way to quickly set up the antenna without cutting or tying knots, so it would be easy to take down, store, and use again. This is not as easy to achieve as it sounds! We had 3 or 4 forays into the field to test different approaches before we finally found the combination that met our goals. Finding the right components was a very time-consuming process, as well. Included are two spools with 1.18 mm black paracord - 30' on one, and 15' on the other. These are used for "guy" cables for the two described configurations. In addition, a spool hanger is provided for the inverted V configuration, to prevent the antenna wire from coming in contact with the supporting tree limb or other support, which would seriously detune and reduce efficiency of the antenna. Also included is a lead weight with carabiner to attach to the 30' or 15' length of paracord for throwing over a tree limb during the setup process. This step must be done carefully, watching out for possible bounce-backs or hitting another person standing on the other side of the support. There are 3 ground stakes to support the two antenna configurations, as well as 3 flags to place where the ground stakes are located, to prevent damage by accidentally tripping over the stakes and attached wire or paracord. Finally, there are tags that can be attached via a clip to the paracord or antenna to men it visible to anyone walking or running in the vicinity. Of course you would not use these in a true stealth situation.  The Application This antenna and setup kit were designed specifically for QRP rapid deployment and extraction, for use such as POTA, Field Day, and portable operation. Thus, the antenna and setup kit are lightweight, and stealth when needed. The heaviest item is the lead sinker used as the throw weight. While a local rock can be used as a weight, it is hard to attach a carabiner to a rock! Thus, we include it in the package. The zipper 14 oz heavy duty waterproof canvas pouch is 13.3" x 9.4" and weighs a mere 1.6 pounds fully loaded with the antenna and setup kit. Also included Also included in the package are two additional cables, to attach the antenna to your MMX or DMX transceiver.  One is a 3 meter (9.6 feet) SMA male to female LMR-100 cable, and the second is a 8 meter (26 feet) SMA male to female LMR-200 cable. These cables can be combined for a total of 13 meters, or about 37 feet length. All you need to go on the air is a QRP transceiver, such as the MMX Multi-Band Morse Transceiver. For power, consider the SuperPower Solar Battery System.
