Current setup :
RF from 2 decoders to a Triax 1-4 splitter. 3 of those go to various parts of the house, 2 with a Triax TV link, 1 without. The 4th goes to an Ellies 1-4 splitter. The 4 outputs from that goes to other parts with no TV link

Problem:
Tried to install a tv link on one of the outputs of the Ellies splitter. Led not lit. Tested the tv link on one of the working feeds, no problem. Tested on each of the other Ellies feeds, same issue.

So... up into the roof I go. Tested the tv link directly on the cable going to the Ellies splitter. Same issue. Check the connections on the Triax splitter and noticed a 50VDC-BLOCK connecter between the Triax splitter and the Ellies cable. None of the other RF OUTs have this. So I assume this is the culprit.

Question:
Since I'm a plug'nplay kinda guy, I tend to be careful around things I know sh*t about :) So...
1. can I just remove that block ?
2. Will that resolve the TV link issue ?
3. Any danger to the devices connected to the Ellies feed, or anything else for that matter ?

Thanks for reading :)

Very likely. Question is why was it installed - methinks probably to prevent loss of power needed for the splits that use a TV LInk, the DStv decoders have been known to supply on the edge in that regard (may have been decoder age related).

I'm sure you recall that we are warned about raw voltage for TV Links possibly causing damage to other equipment, but doubtful. Voltage is IMO too low and never heard of any incident in all my time involved in this industry. Maybe send a PM to Geoff?
I have allowed unprotected TV Link power into my system before with no apparent effect.

You could instead take a feed directly from the last Triax output that's not in use, but I presume that would mean a lot more coaxial cable.

Likely to, unless the total use of power causes too much loss now.

Not sure I'll help further, very rusty these days ;- )
 
As a rule of thumb I only used splitters with the DC power pass through, and any amplifiers needed to be TV link compatible. The Ellies (RIP) red amplifiers did a pretty decent job, SpaceTV also stocks a decent unit.
 
ok, so both the existing ones are still working. Can get one of the Ellies feeds working so far, the others still remain unresponsive. Not sure which Ellies splitter is in use, must be at least 15 years old. If that's the problem, I have this one on standby if that will help.

TV link will only work with the RF source plugged into the center top pin, and eye plugged into the bottom left pin.

It might have just one DC pass on it, or as mentioned the power could now be insufficient with all those TV LInks attached.

@Segg is talking about the possible replacement (pic). If there is a lack of power then that other splitter won't make a difference.

This one sees to have DC on all outs ? I've moved the new TV link from feed to feed to see if that makes a difference... So only 1 TV link active
