Antenna for Motorola XTS500R?

Mercenary · Post by **Mercenary** » Tue Jun 14, 2005 11:55 pm

Can anybody advise me if Motorola makes an antenna for the 136 to 174 Mhz band or at the very least, one that covers the 2 meter ham band.
I would like to find a factory Motorola stubby antenna if possibly but will take a helical antenna as well. Thanks.

Here's every single Factory Motorola VHF antenna made for the XTS series.

Dipole Antenna, VHF Band 136-174 MHz 8505518V01 (8.1"/Red) (Wideband) (NAD6563)

Helical Antenna, VHF Band 136-150 MHz 8505644V01 (7.8"/Yellow) (NAD6566)
Helical Antenna, VHF Band 150-162 MHz 8505644V02 (7.3"/Black) (NAD6567)
Helical Antenna, VHF Band 162-174 MHz 8505644V03 (6.9"/Blue) (NAD6568)

Helical Antenna, VHF Band 136-150 MHz 8505834W01 (5"/Yellow)
Helical Antenna, VHF Band 150-162 MHz 8505834W02 (5"/Black)
Helical Antenna, VHF Band 162-174 MHz 8505834W03 (5"/Blue)

Stubby Antenna, VHF Band 150-162 MHz RAD4194A (3.55"/White)

This one is a good compromise, to cover the upper end and the ham band with one antenna. Just below the ham bands (136-144) its performance is limited a little bit, but at 144 and at 174 in daily use there is no remarkable difference to the recommended antennas.

I'd recommend the wideband dipole. They're long and inflexible which is a bit of a pain, but I see a noticable improvement in coverage out in the boonies.

My XTS3000 with big-ass NiMH battery and wideband VHF antenna still works just fine in my bunker coat.

I know it and I have some of them, but I hate them, they are big and ugly :)

Thanks for all the replys, i'll probally go with the Helical Antenna, VHF Band 136-150 MHz 8505834W01 (5"/Yellow), it should work fine for my 2 meter needs. Thanks.

I take it that the Helical Antenna, VHF Band 136-150 MHz 8505834W01 (5"/Yellow) will also work on the Motorola HT1000 without damaging the radio due to a high swr or something else?.

In case the HT1000 uses the same connector (it should, when it is similar to the european GP900, the version I know better) it works perfectly.

Yea, all the antenna's I listed are all for the Jedi Series (HT1000/MTSx/Visar) XTS Series and the new PR1500.

They were made specifically for all those radios.
No Damage can be Incurred, unless you're using a uhf antenna on a vhf radio, or visa-versa

I also forgot to mention the color after the model number is not the color of the actual antenna (they're all black) but the color of the plastic insulator on the bottom base of the antenna.

Even when using the wrong or no antenna at all - the radios survive this. I never have seen a modern Motorola radio in normal power classes (below 25W, like normal in europe) with blown PA from wrong impedance. It happened always from lightning, from wrong polarity or wrong voltage source.

Well it's never happened to me, But from what I've read in the past, wrong antenna could result in a Blown PA. (could being the key word I guess).

Then again, why would you wanna use the wrong antenna on your radio in the first place?

I'm using the 150-162 split antenna on my HT600, on 144 MHz Tx and after about 10 minutes of talking off and on the radio will get really hot and it seems as if it even heats up the antenna solder because the antenna will stop working (no Rx, but still Tx'ing but not into the antenna) Any thaughts?
