Why DiSEqC Switches Fail - Satellite TV

A look at some reasons DiSEqC switches used in satellite television systems might fail.
DiSEqC switches are used to route multiple satellite LNB signals to a satellite receiver through one coaxial cable. They are electronic switches that automatically select the correct satellite as you change channels.

I must add that is important to ground your switch, splitter to protect your satellite system, and a TV-Sat Surge Protector. A good example of protector is the: TV-Sat Surge Protector: SIGNAL (F-plug/F-socket) the frequency range is between 5 - 2400 MHz ideal for Antenna, Cable and Satellite. You can also use the AMIKO LIGHTNING PROTECTOR which works between 5 - 2150 MHz.

Last year I replaced my 4 input Diseqc Switch with an 8 input Diseqc Switch to connect 6 LNBs. Both are made by AMIKO. The problem is that the 8 input switch isn't weatherproof like the 4 input so rain, snow and sunlight can damage it very hard. The final solution was to hide them under the rooftop and solved the rain, sunlight and snow problem.

i just read the other day that you can use dielectric grease on coax connectors to help repel the water from weeping into the threads, might be something to try i haven't done it yet to my connections

Nice info. Got lot of information about satellite broadcast

Very informative as usual. I've been out of the loop for a while. (My last dish was a C-cup) A place that looks like I'm going to rent has a crazy dish farm on it's roof. There are at least 5 KU size dishes pointing in all sorts of directions. Only one points southish. I do know that the previous occupant was getting India/Asia broadcasts so maybe that explains it? So the point of my post. A great way to weatherize your connections, switches, ect is with electrical boxes. They are available in several sizes, easily mounted, and you can place hinged covers with gaskets on them for easy access. Easy to obtain coax feed through bushings fit perfectly in the knock out holes. Just glue them in. I use silicone. I've done it on several installations.

If I'm using a lnb with c and ku feeds, when I do scan on ku side I always disconnect c band cable because for some reason c band channels will drift over and show up as ku channels.

What can I do with my new decoder not support 8 ways diseqc switch.. not bringing out frequency signal when I put Rf wire connector

Hi Bro.
I'm very happy to watch your explanation regarding diseqc switch problem.
Recently I was baffled by frequent problem with this switches either failure at Port 1 or failure on many ports.
Your explanation regarding handling, safety or covering this switches saved my day.
One more thing at the end of your video is regarding the switching of C-Band and Ku-Band signals was something new to me.
I wish to get your opinion regarding the installation of lightning arrester. Basically there are video explanation of the installation of this light arrester either right after the diseqc switch or before the satellite receiver.
Can we install it right after the LNBs as frontline before arriving at the Diseqc switch during thunderstorm?
Thanks in advance.
