A spectulation concerning the aerials in post no. 105:
I wonder if the original aerial was the combined one - presumably at the top of the mast. It may have been a TV rental type installation which only gave so-so ITA reception. Then later the owners changed TV (to one perhaps not so good in a fringe area) or just wanted a better ITA picture or perhaps new owners took over the property. At which point somebody moved the combined aerial down the mast, mounted the B & L at the top and, by dint of using a diplexer, just used the combined aerial for its Band I reception. If it was weak ITA reception I wonder why a B & L 9 element was not used given all the trouble of installing a new aerial? Mind you, combined aerial types were never as good on Band III as ones specifically designed for Band III, so perhaps a 6 element Band III just got over the acceptability threshold.
Who knows
