Subject: DTV Reception Problems (2/2)
(about 10'apart in the Storage Area), the load (4 tuners, 6 TVs), or
slight differences in the two antennae (I did buy them several months
apart).
The 'TV system antenna' needed help with receiving Ch 4 (LIS, on the VHF
band). Added a monopole antenna from an old TV, using a combiner to add
the two signals together. Greatly helped in the reception of Ch 4, not
so sure was that great an idea for the rest of the (UHF) stations. Did
find out there's such a thing as a diplexer: looks like a splitter but
one tap is VHF In and the other is UHF In; output does combine the two
signals but keeps the bands seperate (UVSJ).
It was also suggested some very strong and very close-by (at the same
antenna farm as Ch. 4 - about 2½ miles away) could be overloading the
system, and to use two, possibly three, FM Traps. Two seems to do the
job here.
I also changed the monopole antenna to a 'regular' rabbit ear antenna
(fully extended for Ch. 4 at VHF-Low). That switch seemed to have fixed
all of the receiption problems with Ch. 4.
The changes were made in steps, so not just one of these changes did the
trick but all of them combined fixed the various receiption problems. Admittedly
still have some pixellation/dropouts, but they are less
severe and briefer than with the original system.
and less
