Antenna cable upgrades - how far is sensible
Posted by Timbo in Oz on April 30, 2003 at 21:44:10:
About 5 years ago I went through the task of upgrading my antenna array and feeds for FM and TV including Band 1V UHF. The usual advice is that for runs less than 100ft RG6 is just fine. Even counting the 4 runs to sep. outlets I would not be much over that if at all, it is not abig house being around '16 squares'.
A Higher stronger mast, New Fuba 4-way mast-head combiner - [VHF-BII (FM), plus UHF IV, UHF V, and VHF111 for TV].
[To mount a VHF-TV Band111 phased array antenna, a long with the existing long FM job and a 24 element UHF BndIV yagi. Along with an eye bolt and deck lashing points for rope to raise and lower a new 'random' long-wire AM antenna.]
But then I was offered a partly used reel (big) of RG11 by the comm's guys at work. 'big tits' cable.
Though I used the easier to bend RG6 to connect each antenna to the combiner, I did use the RG 11 for everything else: the down-lead and onwards past the big 4-way splitter (with coils) to each of 4 outlets in the house.
Now RG11 is just overkill isn't it? It didn't cost me anything though!
Well, using standard 75ohm coax type with the same FM antenna the UHF antenna, an older combiner, the same splitter, and the same outlets, I am sure I had noticeably more noise.
Further the RG11 installation also sounds a lot better on FM,and TV is very good too. Am I kidding myself? Or is the Fuba 4-way combiner really responsible? The extra VHF antenna is band pass filtered for Bd 111 by the Fuba.
