In respect of relative feeder costs, these Belling Lee advertisements from 1947 provide some clues:
L.336 unscreened 75-ohm twin was £0.031 per yard
L.600 coaxial 75-ohm was £0.062 per yard
L.1221 screened twin was £0.088 per yard
L.1221 was most associated with the Eliminoise radio aerial system, but was also stated to be suitable for TV use, so it looks as if it was Belling Lee’s contender in the 75-ohm screened twin class.
BICC also offered a full set of the three types, but I have not seen any pricing information:
Cheers,
Steve
