Being that I work in the CATV field, I use common 75 ohm splitter
arrangements for my remote receiver applications. They are cheap (free
for me) and are easy to implement. Using a splitter of this type
doesn't require any special length to be used from the splitter to the
receiver; whatever is convenient is fine.
At my one site where I use 250+ watts of transmitter power on VHF, I had
discovered that my 4 way CATV splitter for my UHF link-back receivers
was getting warm. I am not using any preselector or filter prior to the
splitter and had found that 2.5 watts of VHF energy was being dissipated
in the splitter. I figure this was happening as the UHF receivers were
likely shorting out the VHF energy and it had to be dissipated
somewhere. While the splitter gets pretty warm, it hasn't burnt up
yet. I do have a helical preselector that I plan on implementing before
the splitter. It's 2 sections should eliminate the power reaching the
splitter and it should be able to dissipate the energy better.
