BASE ANTENNA WHAT IS BEST
I need some help choosing an antenna for my
base station police scanner. any suggestion (pros or cons) would be appreciated |
I agree with Nelson. If your looking to listen to your local PD then the
discone is the way to go. Wide bandwidth. Easy to install. "jaffo1" wrote in message .rogers.com... I need some help choosing an antenna for my base station police scanner. any suggestion (pros or cons) would be appreciated |
I know a few have suggested discones....but they are really for
horizontalradiation, you need vertical polarisation for police. Try a 1/2 wave dipole, easy to make. "jaffo1" wrote in message .rogers.com... I need some help choosing an antenna for my base station police scanner. any suggestion (pros or cons) would be appreciated |

I have one of these, and while I'm not expert, it does a wonderful job for
me. I've never used a discone, so I have no way to compare the two...

Too bad the ST-2 omits the milair freqs :~( I almost ordered one till I
read a DETAILED frequency coverage (30-50, 148-174, 440-470, 470-512, 800-912 MHz) Most stores list it as 30-1300 which isn't quite the same... "PowerHouse Communications" wrote in message ...

This is what you want. Will blow away about any other omni antenna out there. Light years ahead of a discone. http://users.cis.net/kingpop/Scanner/Scantenna.htm BDK ------------------------------------------------------------------------------- Not quite light years ahead of a discone. Last year I put up a discone on one side of my house and a ST 2 on the other side, fed them both with RG 6U double shielded. Had them feeding a Yaesu VR 5000 alternately. The discone was the one that had the vertical element on top. On 30-50 I could tell no difference between the 2. But I could use the discone on 6 meter fm with a 1.9-1 swr. on 148-170 they appeared to be the same. On some freqs the ST 2 was a tad, and I mean a tad better. ON other signals in VHF (i.e.144mhz ssb amateur) the discone picked up distant ssb chatter while the ST 2 picked up nothing. On the discone I can use on 2 mtr. fm with almost a flat swr. On 440-470 they apeared to be the same for all intent. Although I can use the discone on 440 fm with a 1.5-1 or so swr. On the 470-512 area there is nothing to listen to around here so thats a wash. But on 800-912mhz the discone worked quite well and is somewhat resonant there, while the ST 2 seemed to be about deaf in this area. If you live in an area that gets freezing rain and wind, even the new improved ST 2 will not last. Its too fragile. I have never had a discone come down. After my tests I took down the ST 2 and sold it, and still have up the discone. There is no substitute for being resonant at various points on a freq plot. The ST 2 basically fakes the radio as far as impededance with the 300 ohm transformer. It hardly blows the discone out of the water, like I hear so often. Advertising hype. Jeff |
However it is half the price and includes the feed line and shipping.
It seems by the reports for monitoring the basics its a appropriate antenna Doug "Jeff" wrote in message news:U060d.158329$Fg5.72937@attbi_s53... This is what you want.
