    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Hello All:

Is anyone using a Comet GP-9 dual band vertical for general
scanning? I am thinking about purchasing one for dual useage and
just wondered if anyone has tried one for scanning.

Many Thanks,

ScannerEd

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.
