trapped dipole 20-40  Time owned: 3 to 6 months
Always a builder of my own wire antennas I decided to try this trapped dipole out. As a city dweller we are limited for space and the ragged look of multi-wire antennas is just not permitted. It was shipped as promised and packed nicely. There is no assembly just put it up and make the adjustments. As expected with loaded antennas the bandwidth on 20 is very broad while on 40 is about 100KC.

The design is straight forward and in actuality the lengths supplied were a bit too generous for resonance. In my installation as a horizontal dipole I found the measurements to be 16 Feet 6" to the trap and 38" after the trap for 40 meters. With those measurements the antenna resonates at 14.150 and 7.050. A perfect fit for the CW operator. The total length stated is 42 Feet but mine was 40 feet including the traps and ends.

It loaded for me fine with 500 Watts out. A great little antenna for the limited space Ham who wants a quick and easy installation.
