    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.

Hey Group.

Been trying several different preamps on my RS Discone @ 35' to help bring in some distance aviation traffic, not really finding anything that works good. I was thinking about adding this one at the antenna: ARR P30-1000/11VD

Has anyone tried this?

Also thinking about a yagi instead of a Discone.

Ideas?

Thanks,
Chad

If you live in an RF rich environment it will produce all kinds of extra signals to clog your receiver, unless you put a band pass filter in front of it. If all you want is VHF air band you can do a lot better on noise figure, a preamp for that specific band should be well under 1dB. If you get one of these filters:

you can shop for preamps with a better noise figure and you could probably get by with a lower 1dB compression point. Stick everything in a box at the base of the antenna and it should work well.
