First, you are off by a decade, the Texas DPS moved from 1658 kcps.
to 42.9 Mc. in 1949. Prior to the move, they used
(very successfully, I might add) a earlier version of Reg's antenna,
which was a 10 foot bamboo pole helically wound
with waxed cotton insulated bell wire. IIRC, the winding was spaced
about 1 to 1=BD wire diameters apart . The
transmitter was directly connected to the base of the antenna with a
short piece of 8 gauge wire, so there was no SWR to
worry about, and final tuning of the antenna was done in the
transmitter output pi-network. Black '41 and '48 Fords
with 10 foot cane poles on the rear bumper brackets, brings back
memories.

I read somewhere that in the 50's, law
enforcement 2-way radios operated close to our 160m ham band.
Wonder
what kind of antennas they used on the police cars. Of course the
distances they were interested in are different from hams.

Hi C. George, Thanks for the interesting info. I certainly did not
know the 160m radios dated to the 40's. My memories of 1950's law
enforcement are "Highway Patrol" starring Broderick Crawford on the BW
TV. I remember watching him standing outside his police car and saying
"10-4" into the mike. Then, he would sometimes put the mike to his
ear, as if it were a speaker.
At the time I didn't wonder about the antenna on his car. I would
expect from your post it would be 43mhz. I don't remember if that show
was any good or not?
