I have the commercial version and it works very nice in the 460-470MHz range but VHF is centered at 155MHz and is much ess than 1MHz wide before the match goes through the roof. It would not be useable for transmitting in the nearby VHF marine band or MURS or 2m amateur band. I have not compared it to anything yet for receive only but I can possibly do that sometime this week. I suspect it would do better than a Discone across the VHF hi band. I have a spare GP-9 commercial version that I would sell at a reasonable price.
