The 10 through 80 Meter AlphaLoop with 6:1 vernier reduction drive offers you a light 10-40 Meter 30 watt PEP SSB (approximately 15 watts CW) transmit/receive antenna in a small package that deploys in 2 minutes. The 40-80 meter Booster Cable enables coverage from 3.5 through 7.0 MHz at 20 watts PEP SSB, while simultaneously boosting performance on 40 meters beyond what all other Magnetic Loop Antennas can deliver.
"I just had a reasonably long QSO on 80 m from Adelaide South Australia to Caragabal NSW which is a distance of almost 1000 KM. The alpha loop was sitting on my desk next to me inside the house (under the iron roof). My signal was 5/9. Now I really believe it works - Joe VK5FBHE".

6:1 Vernier Reduction Drive
Outer Loop with continuous frequency coverage from 7 MHz to 29.7 MHz or 3.5 MHz to 7 MHz using marine sealant and crimped & soldered Silver Plated PL-259s, which is the same technique used to build MIL-SPEC connections for the U.S. Military
Mount - Integrated mount with 3/8x24 & 1/4x20 threads
Silver plated SO-239s are milled and formed 100% in the U.S.A.
Alpha Match enclosure - High voltage enclosure
Tripod - If you do not already have a tripod with a 1/4-20 thread on top, then we HIGHLY
recommend your purchase the optional tripod, which fits in can fit in the optional duffle bag, and deploys under the loop (making for approximately 6 feet to top of loop)
Duffel Bag - Easily holds tripod and all loop components. Dimensions in inches - 12"x12"x3.5"
Weight: Antenna with included Selfie-Stick (3 pounds), Optional Tripod (1.3 pound), & Optional Canvas Duffle bag (.8 pounds)
The Coaxial Alpha Loop Antenna is pedestrian portable via the included Selfie-Stick or you can mount it on the optional tripod.
This is perfect when you need a High-Q directional HF antenna with low noise capabilities. This is the only Commercially available loop that uses an inner Shielded LMR400 Faraday Loop, which lowers RFI by shielding the loop your coax connects to. Also included is the LMR400 based outer element of the Alpha Loop.
Assembles and disassembles in 60 seconds. As this antenna is a loop, there are no taps on coils and no counterpoise wires needed. Has a built in tuner that allows you to easily match the antenna for transmit and receive from 7 MHz to 29.7 MHz or 3.5 MHz to 7 MHz (80 Meters through 10 Meters). High noise rejection is also one of the favorite features of this antenna for many operators in RFI prone environments.
HOW DOES IT WORK?
The Coaxial Alpha Loop Antenna appears as a large resonant circuit to your transceiver. The loop is a large single turn inductor of the circuit. Due to the large size of the inductor, radiation of your signal very easily takes place.
The AlphaLoop Booster Cable enables your 10-40 meter Magnetic Loop Antenna to transmit and receive on 60 & 80 meters. The AlphaLoop Booster Cable also increases the efficiency for 40 meters.
The Booster Cable consists of a specially tuned section of Times Microwave LMR-400 coax plus a double-female SO239/UHF connector that connects to either PL259 on your 10-40 meter outer loop, resulting in an increase in efficiency from the double loop configuration. The Booster Cable is easily installed or uninstalled with Velcro straps.
ABOUT THE INDIVIDUAL COMPONENTS
Outer Loop: Constructed from LMR-400
Inner Loop: Shielded directly fed faraday loop that remains rigid to enable stable tuning and prevent SWR fluctuations.
Variable air capacitor: No RF conduction currents flow through the bearings of the rotor on the variable air capacitor that is constructed using dual gang split stators.
Connectors: All connectors are silver plated using the highest quality connectors available
Housing: High voltage enclosure
Optional Tripod: Integrated mounting point for antenna
Optional Duffle bag: Custom duffle bag holds all components with room left for gear
Optional Large Duffle Go Bag
