Triax UHF Aerial - info
Dear All,
A few years ago I was given a Triax UHF aerial whose lashings had finally failed. The question I'm asking is what Channel range did it cover?
I don't have a camera to take a 'photo but here is some information on it:
It is a (Triax nomenclature) "18 element" design, which has a six element barred reflector and a 'squashed' folded dipole, and 11 plain directors.
It is end mounted, with the boom split into two equal lengths making a total length of 1360mm.
The reflector element width is 420mm. The outermost director length is 130mm.
It has a printed circuit balun in the junction box.
The aerial was originally pointed at the Ridge Hill transmitter and I reckon dates from the early days of dual analogue/digital transmissions.
I've looked up Triax's recent catalogue and the only 18 el design of a similar style uses a centre mount trombone system.
The aerial is probably a Wideband design, but if so was it a 21-68, or was it a 21-60 design since Triax's Danish home-land only used TV upto channel 60.
I must say the dipole size made me wonder whether it could be a group E design.
Perhaps somebody has a Triax UK catalogue from about 2005, that may answer the question?
