10-40 Meter Alpha Coaxial Loop is a small HF transmit receive Magnetic antenna

This 3 foot wide Alpha Loop antenna is perfect for those operating Condo, SOTA, Beach, RADAR, or any place you need a High-Q directional HF transmit/receive antenna with low noise capabilities designed into the system. The LMR-400 based element of the Alpha Loop offers you a light antenna in a small package, which deploys in 60 seconds!

Loop with Continuous frequency coverage from 7 to 29.7 MHz. Maximum Power - 20 watts PEP SSB. Field Bag dimensions in inches - 12"x12"x3.5.

Weight of the antenna - 1.5 lbs. Connection - SO239 directly fed at the inner loop. Mount - Integrated 3/8x24 bolt & 1/4x20 nut. ABOUT THE INDIVIDUAL COMPONENTS Outer Loop: Constructed from LMR-400 Inner Loop: Shielded directly fed faraday loop 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: IP54 Rated enclosure protects all circuits Tripod: 3 foot tripod with integrated mounting point for antenna Duffle bag: Custom duffle bag holds all components with room left for gear.

EHam Reviews of the Alpha Loop antenna line. Assembles and disassembles from the included field bag 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 to 29.7 MHz (40 Meters through 10 Meters).

High noise rejection is also one of the favorite features of this antenna for many operators in RFI prone environments. The 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.

Better coupling will still be the result of using a shielded coupling loop. Where return-loss (VNA parameter S11) increases rapidly when the distance is increased from 0 to 2-3 cm (1), then becomes flat with further increase in distance. Over the initial distance increase, the shielded coupling loops has about 6 dB less return-loss, i. BETTER coupling than a non-shielded coupling loop.

Additionally, shielded coupling loops had slightly better SWR than the unshielded coupling loops, which yields greater ERP! The Alpha Loop Antenna is tuned on 40 through 10 Meters by turning a single knob at the antenna. Simply tune for the loudest noise floor from your speaker, then fine tune with either the SWR indicator tube that is built into the Alpha Loop, the SWR meter in your rig, or use an antenna analyzer.
