M-20 Active Shortwave Antenna

The Monitor Systems M-20 Shortwave Antenna can be tuned throughout the range 6 MHz to 21 MHz, with the range easily extended by shortening the whip. This antenna is designed specifically for use with low impedance ( 50 - 75 ohm) receivers, and provides >30 dB gain, as well as filtering out unwanted QRM.
It comes complete with the standard bracket to mount the whip directly on the tuner, as well as an L-bracket clamp to mount the antenna portion on a pole outdoors (extra cable not included).
Made in Canada

Only $99.95 Canadian


These antenna are manufactured by a local company, who approached us as a retailer. The design is unique as the amplification is only after the antenna peaking, thus you are not amplifying the noise. Our building is right beside the ac mains for the town, so we have poor reception at the best of times. What sold us on this antenna was simply performance. We were testing 2 radios side by side, one on our vertical (mounted on the roof), and the other on the M-20 sitting on top of the radio. It pulled in almost every station our vertical did - it would beat the vertical hands down if we mounted the M-20 whip up on the roof.
