Lately I have been scavenging bits and pieces and partials of KT 34 antennas.
I have managed to put together a second KT 34XA to match my first one and it
works well with a typical SWR.
One of the acquistiions I made was a new partially assembled KT 34A which was
manufactured around 1982 according to the material I got with the antenna.
The dimensions of the KT 34A vary quite a bit from the dimensions of the KT
34XA for the A, B and C measurements.
I have checked several of the KT 34 A s that I just refurbished and
reassembled and all of them have flakey SWRs. Changing out the baluns did
not change anything. I am very familiar with the KT 34XA antennas since I
have owned a KT 34XA for years and went through all the usual suspects where
there might be shorting or lack of continuity with no success. However, the
only manual I have for the KT34 is from 1982, although I have a KT 34XA
manual which is more recent.
My questuion is this. Were the dimensions for the KT 34 A changed over the
years. In my manual:
Reflector: A...60.5, B...47.5, C...28, D...18
Rear driven A...55, B...47.75, C...27, D...21
Front driven A...45, B...43, C...26, D...18
Director A...51, B...43.25, C...24.5, D...20
Do these dimensions vary from the measurements in later manuals?
