Motorola and portable radio antenna connectors

[Cam]

What is the deal?
Is there some logical reason that I just don't see why Motorola can't use the same connector on their whole line of portables? We have a wide range of portables in use or that have been replaced and are now sitting. We when from UHF HT600's and MT1000's to HT1000's, MT2000's and MTS2000's and now have HT750's and HT1250's in the mix. We at one time piggy backed on a 800mhz LTR system for project and used MTX8000's and Waris MTX's loaded to us by the system owner.

Based on this and radio's that I have owned myself, i fail to see what the reasoning is with the connectors. It's not like they came up with a great new design and started using that for everything. They seem to switch back and forth. Even the Waris line uses different connectors in the same line.

Can anybody clue me in on this.

Just a guess but personal preference of the head of the design team? Doesn't make much sense. I like the SMA ones because you can get a proper connector for it instead of an adapter that has no real ground connection.

I had that idea as well but who knows.

Kind of on the same subject; I have two UHF 1/4 waves here in my hand. One is for an HT1000 and one for our HT1250's. Both say they are the for the same band split but the HT1000 antenna (sma) is about an inch shorter. Most be the power of the little ball on top.

My guess would be cost.

Loss factors at UHF and above are considerably higher than that of VHF.

If you look at most VHF radios, they just have a threaded nut connector. 800/900 units ALWAYS have the RP-SMA connectors on them.

My 220MHz HT1250 has an RP-SMA connector on it.

The Jedi series radios probably received those connectors because of the tier of radio they are - high end, public safety.

Somehow our guys never have any problem swapping antennas between models. But, I think some of them could screw a popsicle stick in without any trouble.
