    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.

Am interested, and have read good things about the scantenna (st2). I read the specs from antennacraft and the output impedance is 300ohm. I think there is a transformer included which then drops the impedance to 75ohm.

My radio - Icom R20 has a BNC 50ohm. Well i guess you know where i am going with this.

Wont the two different impedances create a loss?

Is there a way around this?

Thank you

They come supplied with a 4:1 300ohm to 75ohm balun and RG-6 coax. Good VHF/UHF but a little weak on 800. You can add length to long bottom element to drop coverage on low band. Good Luck.

The small difference between 50 ohm and 75 ohm is mostly irrelevant on an receive only antenna system.
