any idea how I can get ahold of a motorola apco25 mobil ant?

[dizwiz]

Im having antenna issues for mobile monitoring of Ohios APCO25 MARCS system.

Im getting a lot of partial audio decodes when monitoring Ohios MARCS system mobilely. I want to go to an exterior vehicle antenna.

Id like to get a hold of a commercial MARCS mobile antenna to mount on my car. Im hoping it has a BNC connector on it too.

I know antenna design is complex and im sure the guys at Motorola have their antenna design ironed out and optimized for MARCS.

Any idea how I could get one?

Id contact Motorola, but I dont know what the radios are called...

Mot doesn't make antennas. You can use Maxrad or Scantenna (or whatever it's called) and some various other ones.

Whats the ones the cops use (ohio highway patrol)

they apparently work.

looks like its in the 800mhz range... so any 800 mhz antenna should work... i have a 800 Antenex Phantom on mag mount on my truck... works great for the 800mhz p25 system here in Minnesota... any you can choose what connector you want on the end... i installed a bnc on my mag mount and hooked er up to my 796 and walla...

I have a couple Motorola branded antennas. They work well but other brands like the ones you stated are just as good or better, are probably more easily obtained, and offer more variations.

I think Motorola branded are made by Maxrad. I know Motorola doesn't make them now for sure. They could have made them a long time ago. How old is that antenna?

I bought them both off ebay but they came in Motorola packaging with current Motorola part numbers. They were definitely genuine Motorola because I checked them against MOL to see what the original cost was.

I will see if I can dig something up with a part number on it. I have one vhf and one 800 mhz.

Specific antennas for trunking systems do not exist. What you are looking for is an antenna designed for the frequency you are listening to, in your case 800mhz. They do of course come in various gains - no gain to high gain, take your pick. Many makes and models are available.

Also make sure that you use a good quality cable and have a good earth or vehicle ground, either at the radio or the antenna cable.
