After trying a discone, quarter wave and 800 mhz antenna, I found a great scanner antenna. This may not be news to some of the more "seasoned" scanner buffs out there, but it's good information for the new ones.

I now use a Comet GP3 2m/440 antenna, which is mounted on a small tower and fed with about 30' of LMR 400 cable. I had previously connected the discone and quarter wave the same way, but the signal improvements are incredible with the Comet.

I can't explain it, because it goes against alot of the antenna length theory information, but all bands, including VHF Lo, Air and 800 are excellent. I am really surprised about the 800 mhz., as this makes no sense at all. It's better than the dedicated 800 antenna I had up there.

I know there are some who are going to want to fight the fact a ham radio antenna is not designed for scanners, especially VHF Lo and 800 (Just like I fought it!), but just try it. You'll be surprised.

I've got one on my tower @ 85 feet as a secondary/backup 440 antenna. It really does work well. I'm impressed.

These are generally perfectly fine for scanning. Most of the time scanner frequency bands are higher than ham bands, so you can tune the antenna by trimming (though these fiberglass-enclosed ones are usually notune)

I rock a Diamond F22A vertical for 2 meters and VHF and it has stunning performance on VHF high. For a year, my main scanner antenna was a $15 dual band mobile on a pole, with the elements swapped for coathangers (so I wouldn't muck up the original elements by hacking them up) - worked perfectly.

I used the Heathkit dual 5/8 wave 2 meter for my scanning years ago. Worked excellent for all bands VHF-Lo & HI, UHF and 800

Remember... we're listening, not xmitting

Please don't hijack the thread, bob...

Anyway the studs won't do much harm, but that 58U patch is going to add some attenuation - maybe not too much, but if you are doing weak signal work, such as Milcom, every db is precious.

Go back and replace that patch and RG8 with a complete run and get rid of the annoying 58U. It's almost worthless on higher freqs anyway 73s Mike

No kidding?
Interesting.
What brand discone were you using?
Still happy with the stick?
