I have a triple lnb dish that is rigged to feed 4 seperate tv locations. I have an antenna and a diplexer. The antenna and dish are connected outside near the dish with a diplexer.


Question is if I wish to feed several more tv's, do I need several more diplexers and a spltter for the antenna before them or can I just put a splitter after the diplexer and forget about the four seperate feeds from the dish? What are the +/- of different ways?

Get a 5x8 multiswitch. You don't split a dish connection. The 5x8 takes the 4 lines from the dish and one from the antenna and outputs 8 diplexed signals. It's a neater solution and the money saved on splitters and diplexers will probably pay for it. If your dish has an internal 4x4 multiswitch or you don't want to bypass a 4x4 multiswitch on the back of a dish, you'll need a 5x8 cascadable external multiswitch like the Terk M58 or the Eagle Aspen S-4180-GX+. If your present 4x4 multiswitch is external, you can bypass it and use any 5x8.

mine is a triple head multi satellite LNB with built in multi-switch for four independent outputs... The LNB with multi switch is basically one piece and it bolts directly to a hollow LNB arm, the four wires slide inside the arm.

for just 2 or three tv's maybe I should just buy a couple more diplexers.. The terk seems kindof expensive and it has to be mounted inside doesn't it?

You do mean 2 or 3 TVs in addition to the 4 already don't you? You cannot do more than 4 with diplexers or splitters. You need a 5x8 M/S and you need to protect it from the weather. My Eagle Aspen is in the attic. You can put it in a plastic box like a Radio Shack kit box. Just put all cable entries at the bottom. Water won't run uphill too well.


See the wiring diagrams at 18inch.com and

Edit add:

On the other hand, after a look around I've seen sites that say the Terk M58 is weatherproof and my Eagle Aspen has a sealer around the cover plate. I believe the units are actually the same and it's possible the sealed cover plate is a new addition making the old warning about weather protection moot. I still prefer keeping multiswitches out of the weather.

no sorry,


I am only using one of the original four. I have only one tv connected to the sat. Other tv's are getting limited basic cable right now.

So the original "rigged" meant capable. Ok. You need any splitters between the antenna and the diplexers. Each TV needs to have a separate line to the dish. That would mean a 1 into 4 splitter between the antenna and 4 diplexers for 4 TVs. You don't split a DSS feed.

thanks greywolf,


Good you told me because I was considering splitting the feed I already use. Now I know better...
