Hi all,

I am looking for some plans to build myself a scanner antenna to
improve reception at home (Base). I am only interested in the 800mhz
trunked frequencies at the moment.

Look on Ebay for a decent 800 mhz yagi. A ground plane on 800mhz is
pointless unless you are close to the xmitter site.

I've seen Cushcraft ones for $20 new in box on Ebay.

Search antennex, maxrad and cushcraft for Yagi.

Your feed line at 800mhz is more critical than the antenna.

LMR400 should be a minimum because loss is so critical at that
frequency.

Get about 30 ft of elevation and a magnetic heading to the xmitter
site off of the fcc database for that system.

I've seen really decent long-range 800 reception with a commercial
800 yagi, fed with a radio shack inline tv UHF amplifier and rg56 quad
shield (satellite) coax with a 50 ft. run.
