800 mhz
LIke the other have stated sometimes 800 can by straight simplex most of the time it will be either type 1 or type 2 or 2i trunk. IN a trunk system if you have a receive of 855.000 even then the tx would be 810.000 or 45 mhz below the Rx CHannel But that will all be changing soon when the npspac and rebanding takes place thanks to nexthell

Hi gfd.... I swear by the Valor ProAm PMM3B. Here is the link I used to order mine:
http://www.universal-radio.com/catalog/scanants/1190.html
There are a couple of threads in the Antenna Forum concerning the PMM3B, the more recent is at: http://www.radioreference.com/forums/showthread.php?t=19122
The little thing has held in the wind storms we've had here recently, higher-than-posted-limits speeds and even hears well when coated with ice (like this weekend's snow). It is so discrete that my wife even allowed one on my POV so I can hear better when driving to and from work (she uses it, too!).... the only problem I had was with the first antenna--the BNC came loose because of repeated connection cycles, replaced that BNC and use it on the POV.

Trying to simplify things, 800 MHz is pretty much like UHF and VHF. It can be used in simplex configurations where it transmits on frequency A and receives on frequency A. It can be used in a conventional repeater configuration, that being it always transmits on frequency A and receives on frequency B. It can also be used in a trunked configuration which is usually a repeated situation (though simplex frequencies may be used in some situations).
As far as antennas go, there is no "best" one. If there was, that would be the only kind around. Antennas are like cars in some respect - some folks love Ford and others love Chevrolet.
