6dB COLINEAR VHF ANTENNA

[a71br]

It is not particularly difficult to make a VHF antenna with omni-directional properties as well as having a 6dB gain*. A "Slim-Jim" antenna is quite popular but only realises about 1.7dB of gain*. I had a problem with my packet radio station and decided that antenna gain was the solution. So now I have a 6dB gain VHF colinear. I also managed to get another 6dB or so out of my old tired-out IC260A VHF receiver with a bit of dexterous tuning.
