• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    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:

Hey all. I was just wondering if I were to hook up an RCA UHF/VHF/FM TV amplifier to my scanner line if it would pose any problems to the scanner in the long run? Thanks.

They work great for a multicoupler. It will not cause any problems...

Multicoupler?? What are you talking about? He is talking about a preamp.

They might work O.K. as a preamp depending on your environment, however, there are a lot better out there.

Aside from overloading the scanner and receiving a lot iof intermod, no. (Scanners need a couple of microvolts of signal, TVs need a couple of hundred microvolts.)

Most non-professional grade preamps I've ever looked at on a spectrum analyzer tend to raise the noise floor a lot and this could actually make reception worse. As Al42 says, TVs need a lot of signal and most preamps have a lot of gain.

The bottom line though, try it, it won't actually hurt anything and if it causes problems then take it back out.
