XPR 6550 - Antenna Band Colors

[bosco836]

I recently won an auction of several used UHF (Low) XPR series radios from an ambulance service that had gone out of business. Most of the radios have the "green band" antenna which, as I understand it, covers 435-470; some have a "red band" which I understand to cover 403-435; and one in particular has an "orange band" which I've never seen before.

Any insight into what band-split the "orange band" covers? Is this just a (faded) red antenna?

In our area, were primarily on the lower side of the 400 spectrum which will likely necessitate the replacement of the "green band" antennas with "red band" ones - but I'm curious about this "orange band" one.

Thanks!

When you say your on the lower side of the 400 spectrum, what exact frequencies are you using? Most things lower then 435 are government systems like military bases and feds.
The Green antenna will cover most standard public safety in the mid UHF range. Unless your someplace like Chicago or New york which may use T-Band channels the green one should suffice fine.

We're operating between 410-420. We're in Canada so have some different frequency coordination rules here than what is commonly found in the US.

Yup there ya go. Your in Canada. Red band it is.

 

[bosco836]

Yes.

Any idea what this "orange band" antenna is that we seem to have acquired?

I just use these NAE6549 antennas. SMA for the JedI, Astro Saber, XTS3000, 5000, & APX. Full 380-520 MHz coverage. I just throw the 6550 antennas in a drawer, as I have no need for GPS.

Any noticeable performance issues in fringe areas compared to the red band antenna?

 

[N4KVE]

None at all. Plus the antenna seems to be more flexible.

It's more than likely a Motorola PMAE4006, UHF 9cm Helical Antenna with 465-495 MHz range
