Antenna Question

[Troop]

APX6000 work radio. Orginally equipped with the long 700-8 GPS antenna. Several of us purchased the OEM Motorola 700-8 GPS stubby antennas......Was told by brass today that it's not allowed. Does anyone have any data on how one receives and transmits better than the other, like with numbers? Thanks in advance!

Not with that exact antenna.

However, on my 800MHz NexEdge trunked system, I've compared the "standard" whips on 800MHz to the stubby Motorola 800MHz antennas, and the stubbys show about 6dB more loss when looking at the control channel.

6dB could really impact coverage on the edges of the system, or inside a building. I -strongly- discourage my users from using those, but they do anyway. I'm not the radio police. But they don't get to complain about coverage, either.

Nar6595 7-800 Gps Antenna For Motorola Apx6000 Apx7000 Apx8000

Is the correct antenna for 700- 800.

Is the correct antenna for 700- 800.

The OP stated that they have already purchased the OEM 700/800 stubby, so presumably he is already familiar with the NAR6595A.

What he's looking for are some real number comparisons between that stubby and the 6000's standard full length 700/800 whips, which is either the original design NAF5085A, or the new design PMAF4040A.

The 6db number is what I saw as well when I was doing some comparisons a few months ago.
