Many compromise antennas are the 6 to 12 foot variety. The Buddistick, SuperAntenna MP1, Pac-12, and a Chameleon (it has various variants) all offer a short antenna with multi band capability.
The key to these antennas is to have an elevated counterpoise. I have done several Field Strength Readings in the field and in a controlled location to try to understand if there is any directionality to its placement.
YES I have found that there is!
Point it towards the station you are trying to work. There is noticeable improvement in the transmit signal that it would be worth the effort to locate the counterpoise accordingly.
I dont think I am seeing much in the way of reception of signals.
A gain of 3 db is the equivalent of doubling or reducing by half your power.
PLEASE NOTE THE COUNTERPOISE WILL WORK A WHOLE LOT BETTER IF IT IS ELEVATED…
