Help Please - Antenna Plans 800mhz?
 

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. I get no reception at with the
ducky and other mobile antennas I have purchased. To get the data
channel to lock in, I have to drive into town to pick anything up. :-(

I have :

BC 235xlt
100 feet of RG6 coax to the roof

Can you point me to some plans?

Many thanks!

I'd get or make an 800 yagi( about 8 or 10 elements) and point it at the
repeater tower. You could build an 800 ground plane too.

What are you trying to listen to at 800 mhz?

Thanks Sarg,

My local Emergency Services broadcast on trucked 800mhz frequencies.

The 100 ft. of RG-6 is going to really hurt your reception at 800 Mhz (at
least 6 db or so).

If interested, I will sell you a MAX 800 (800 MHz ground plane antenna)
CHEAP! It's the first one pictured on this site:

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.
