That being said, I will help where I can and I hope you liked the article. Cable Losses Increase With Frequency The higher the frequency the signal on the coax antenna cable, the greater the signal losses will be. Signal Sloping The difference of signal losses over coax cable length can be very problematic in large TV systems and long cable runs as you have to consider signal losses at different frequencies on the same cable.
Overcoming Signal Sloping Overcoming signal sloping is very important as you may have a good signal on the services that use the lower frequencies and a very poor signal on the higher frequencies. Install Amplifier Before Signal Is Weak You want to install your amplifier in a location where the signal is still of an acceptable strength, before cable losses have taken effect. Satellite Line Amplifiers Simple satellite line amplifiers can be installed which has a sloped signal gain to remove sloping and are powered by the satellite receiver can be installed to overcome signal losses on long cable lengths.
Consider Fibre Optic Cabling For Very Long Runs If you have a very long distance that you need to send a TV signal, consider using fibre optic cabling instead which distributes the signal using light rather than copper conductors.
To do this: 1- Find the highest frequency that you wish to carry through a coax cable.

What would be the maximum cable length of RG6 from the LNB connector to the receiver input before there would be significant problems? Will the available satellite signal strength effect what this this length may be?
If needing to exceed whatever this maximum length may be , are there in-line amplifiers available to compensate? Plywodstatebum SatelliteGuys Pro. I'm running a ft with no problems. Plywodstatebum said:. Click to expand Jan 22, 29 0.
Normally, you lose 8db per ft of RG-6 cable. If you properly peak your dish, longer length wont be much of an issue. We've ran ft with no problems. Keep us posted on how you get on please? This advice from Satcure "WF cable is thicker, stiffer, and has lower losses than the cables above.
Recommended for long LNB connections e. Note, however, that WF is stiff and should not be connected directly to indoor equipment as it can put excessive strain on the connector. We recommend that you use a threaded coupler and a short length of more flexible cable for this connection.
We supply twist-on "F" connectors for this cable. You can not fit a rubber boot to a WF connector so use self-amalgamating tape. WF can be connected directly to the LNB but the same comments about additional weight and stiffness apply. It can put extra strain on the connector and the extra weight can cause the LNB support arm to bend.
Alan Mac Well-known Member. Click to expand Maplin's have both CT and CT coax in but it's a bit pricy, any suggestion where to buy? As the noise figure calculation demonstrates, there is no real performance benefit in using WF over WF for a 40 m cable run and even less for 30 m!
There are also some practical disadvantages bend radius, fitting connectors and of course the price. I would go for WF SamRadford Well-known Member. As stated on that Satcure page, it's better to use a slightly larger dish to compensate for a long cable. I am intending on a 30m run at bottom of my garden as I no like heights. I live in a block of flats and I was on the wrong side for the dish, hence the length of cable.
I used WF cable and a 60 cm dish, on the Lizard in Cornwall, which is just out of the main reception area according to Sky's sat map. Recently I have moved and am now using only 5 metres of cable much easier! I know you are not using Sky equipment, but hopefully this will give you some idea of what you can expect.
It was a 60 quid m roll from Satcure. At the moment, I'm selling both 50m lengths on Ebay ends tomorrow. Best way to connect my Sony and Sky AV equipment to get maximum viewing and sound performance?
