Hello everyone! First time posting here, but I'm sure not the last!!
I currently have RadioShacks Outdoor VHF-Hi/UHF Scanner Antenna (Model: 20-176) and have in fact have had it for many years now..
Recently I've gotten into SDR and decided to give this antenna a try since I usually had good luck with previous scanners (older Uniden Bearcat)
Current equipment:
Newsky TV301U DVB-T USB (Realtek RTL2832U)
Basic RF Amplifier upto 1Ghz +24db
Radioshack scanner antenna (Model: 20-176)
RG-6 Coax cable
The problem I've ran into is this:
When I had the scanner antenna on a ~10' Coax wire, 8' off the ground using my camera tripod, signals were coming in nicely (respectively) and the background noise seemed quiet low..
The other day I put the scanner antenna up 32' using 3-10' 3/4" galvanized steal pipes and a 24" 3/4" PVC pipe which holds the antenna which then the PVC pipe screws into the metal pipe.
After setting it up, and running the software, the signals seem to be weaker, and there looks to be a lot more background noise..
Even on an FM radio station.. The station itself vers the background noise doesn't have much of a level difference.. When I had it on the 10' cable and my camera tripod for testing purposes, the difference in the signal and background noise was much better..
So what am I doing wrong? Is there a reason for the loss in gain and higher background noise?
Appreciate any help!
