A very good answer .
One caveat..... The phase difference into the splitter from each
antenna will be not only spacing dependent, but ALSO frequency
dependent.... In other words, what will work fine at , say, 200 Mhz
may cause a deep null at another frequency, like ,say 300 Mhz.
And this will occur at multiple places in the VHF and UHF bands.
This may not be a problem, depending on where the stations
are located, frequency-wise.....
The best answer is to use a switch between antennae to select
the best signal. However, a splitter/combiner will save having to
throw the switch, IF it doesn't have phasing problems. You just
have to give it a try for your own specific location.
For the record, a properly designed splitter (2way) has an
resistor that is only effective if one of the outputs is not
properly. If both outputs are terminated properly, the resistor does
nothing. The signal will be halved (3db) to each output, PLUS about
a half db of internal loss.
To learn more about splitters, go to a MINI-CKTS LAB website,
(you can google the address). They manufacture these components,
and have many tutorial papers on how they are built, and how they
should be used.
