DL3TU - Topband
We live on the outskirts of the city in a house with
garden of our own. Only the roof offers a little room for small
My antenna consists of a 41 meter long wire that runs to
a nearby tree at a height of about 15 metres. As a counterweight I use
a 16 meter high steel beam on
the outer facade. Most likely this one is radiating as well.
The QRM- level at my place is not catastrophic but still fairly high. S5 at an IF- bandwidth of 400 Hz is standard. Hence I started playing with Rx antennas. They make listening more pleasant. With my current setup I can hear much further than my transmitter signal carries. It occurs fairly often that I can hear the DX, but am not heard by them. Increasing transmit power would be possible but I don't want to be an alligator.
My first Rx- antenna is a "Mini Whip". The second RX- antenna is a shielded loop. Both are located on the roof top as there is no room elsewhere. Due to its size, I prefer setting up the loop only temporarily during contests.
DXCC on Top Band is very close and up to now I worked 25 US states...
