Ken, I am not a signal guys but I believe you are looking at a freq range of 1.5 to 30.0 MHz.

Here's the modern day version of it:

Some references recommend only 4.0 to 30.0 MHz:

Here's the Army TB Sig 154 on antennas dated 1945:

Those antenna masts were used with a number of military radios including the VRC-8, VRC-9 and VRC-10 (VRC-10 used MS-24 and MS-117A sections). They operated over a range of 20 to 53.9 MC. http://www.n6cc.com/vrc-10-rt-68-transceiver http://www.greenradios.com/Radios/American/Old_Family/Sets.htm#VRC-8

Thank you both for the information. I have had the the antenna mounted to the M38 since restoration, but never acquired any military radios.

I don't know but I would imagine the transceiver had an internal tuner, or there was a external tuner and or a balun used with the antenna.

I was thinking about mounting my Yaesu FT857D HF multi band transceiver in the jeep. But I'll probably install the multi band screw driver antenna ATAS-120A

Hi Ken,
Somewhere I read where an enterprising individual
hooked up their CB radio, but probably adjusted the mast
length.

Please see my PM to you.

Take care,

Ken,

With you being a ham, the RT-68 will work on the 6 meter band (50 Mhz... also is wideband FM 20Khz as opposed to 3Khz as used today)

You then use a combination of mast sections to get to the proper length.

That is the setup I have in my M-38, but my problem is I get the radio working on the bench fine, put it in the jeep and the transmitter goes out... something loose I have not been able to find...

Hope this helps...

I've hooked my VX7R up to the antenna and it seems to work ok.

I doubt if I will ever buy any military radios.
