My dad was a policeman in the 40s, right after the war, his operated 40
something mHz. About 8 yrs old and an interest in radio helped me to
remember radio things, many other things didn't have sticking power,
like english and such )

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 1½ 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?
