[Motorola] HT-1000 antenna question

[KCØEJX - Andrew D. Hudanish]

The Expo has an MX style antenna mount.  The HT1000 has a SMA M mount.  The
two are not interchangable.  The MX mount has no RF ground.  The whole mount
is the RF coupling between the radio and the antenna.  The SMA M style has
an outside ground and a center RF pin.  This makes external antenna
connections easier.  Motorola used two different depths of SMA M mounts on
its radios.  The GTX/LCS2000/LTS2000 use a deeper SMA than the rest.

Units that have SMA M antenna mounts:

Astro Sabers
Saber (800/900 Mhz Only)
Systems Saber (800/900 MHz only)
XTS3000
HT1000
JT1000
MT2000
MTS2000
MTX8000
MTX9000
MTX838
GTX
LTS2000
LCS2000
MTX800
MTX900

Units with MX antenna mounts:

MX300 - MX360 (All except 800 MHz)
HT600
MT1000
Saber (All except 800/900 MHz)
Systems Saber (All except 800/900 MHz)
Expo
HT50S
P50
P100
SP50
P200
GP300
GP350
T10
T11


Also, for wideband 136 to 174 MHz coverage, Motorola built a special antenna
for the HT1000 / JT1000 / MT2000 series radio.  It is a dipole type, and is
resonant over the entire band.  It works ok, but I use the band specific
helical antennas made for the HT1000.  They seen to work a little better.

I hope this expleans it a little better.
