Is that for an additional horizontal aerial for the missing channels when I am up to it or a bigger one to give me everything?
Thanks
Not an additional one, just a WB horizontally polarised to get them all.
Can't remember why MikeSh didn't do that, but I expect he will pop along and tell us.
I'm in a more marginal location, com 8 is actually amber on the coverage table, and already had a high gain group A aerial and an amplifier.
I discussed options with the man at ATV (if you want to know more about this stuff have a browse in there:
ATV website ).
I could have spent £70 or so changing my aerial for a wideband, but they have lower gain for any given frequency than a correctly grouped aerial, so I might have still have not got com 7 & 8
and compromised some of the other lower powered muxes to boot.
The other option was a group E aerial and diplexer to put it in parallel with my A aerial. Cost about the same as the wideband because the E aerial was much cheaper than a wideband. Needed some extra bracketry of course, but that's not much. So I did that and it worked a treat
. Unless there is some reason a second aerial can't be fitted this is the way to go as widebands are basically a compromise. It also means that if/when channels 55 & 56 are discontinued the extra aerial can simply be removed or disconnected (if you want) with no need to change the 'main' aerial. (This might be necessary because if the 55/56 frequencies do get sold off for mobile use you are liable to get some heavy mobile transmitter stuff coming in, either through a group E or a wideband. It might not matter, but if it does it'll be nice to be able to fix it by just cutting a cable.)
