Shouldn't be a problem if you use decent quality coax. It would be a good
idea to put it in some conduit, maybe a length of garden hose.

Is there a limit on the length of the cable from a sat dish to the
reciever? I'd like to install a dish at the bottom of my garden (swimbo
won't agree to anywhere else) but it's 75 feet from the house. Would it
work?

I've noticed that posts are missing here and there on other groups. Could
be some servers are out of kilter but . . . your posts are dated *May* so
it'll be another month till they show up here <VBG>

That's what I was hoping to hear, thanks.

Yes will work fine .. thats where ours are and these some 150 foot of
cable with no problems at all:)..

And all in 2 " duct...

Just checked my system date, it was May 2nd. Odd that, I didn't change
it! But Adrian saw it. The plot thickens!

Maybe you've accidently killfiled yourself, you wouldn't be the first.

I almost read that wrong. Thought you said he accidentally killed
himself :-)

Depending on your cable route, you might like to use the Green extra-
tough direct-bury cable. It is more expensive but not easily damaged.
For very long runs you can use CT125 cable which is thicker and has
even lower loss per M. You have to get the correct plugs to fit it and
it is often convenient to connect it to CT100 before it enters the
house as that is neater and easier to deal with.

Either way, make sure that you use foam-cored cable rather than air-
spaced as it does not let water pass through, even if it does get
damaged. (You would have to repair the damage, of course, but not the
whole cable as it doesn't fill up with water)

Would that be assisted newsgroupicide?
I'm using Thunderbird and have never really managed to get the hang of
killfiling...sigh.

E.g. CT125 - you can get it from Maplin.

Yeah keep it away from rats and mice, they seem to like the pvc etc, for
some odd reason.

Dear Mr Guli

If the total cable length is 30 metres the loss at the top of the satellite
IF band will be 9dB if you use ordinary CT100 cable. This is negligible
because the LNB output exceeds the signal needed by the receiver by 25dB
approx. The loss with CT125 would be 7.5dB by the way. But you need to keep
the cable out of permanently damp places. If it is underground it will fail
gradually and will be no good after a few years. Thread it through a length
of 20mm blue alcathene water pipe, or run it along the fence.

I forgot to say. If you do put the cable in a tube, ensure that water cannot
collect in a low point. In practice this means that there can't be a low
point unless it is drained.

I've had 100' of old BICC 363 semi-airspaced coax (used for cable TV in
the early 60s) running down the garden for over 20 years, and is still
seems fine. Most is simply lying on the soil, beside a fence.

About 15' was buried in some garden hose. I needed to re-route this bit
and (not surprisingly) found the hose filled with water. Fortunately, I
had sealed the end of the coax before I pulled it out of the pipe.

I will replaced the coax in a buried duct consisting of a length of 68mm
drainpipe (downspout). This presently carries a long run of 1" flexible
piping which connects a rainwater interceptor in a downspout to a water
butt. The drainpipe will eventually also carry a low voltage DC cable.

Other than trying to prevent soil and stones from getting in the
drainpipe, I haven't tried to stop water getting in. I felt it would be
rather awkward to make a 100% seal. Instead, there is a deliberately
'leaky' joint in the centre, and the centre of the shallow trench (which
was dug for the drainpipe) is the lowest part of the underground run. To
act as a crude soakaway, beneath the join is about 6" depth of sand, so
hopefully, the joint will stay leaky, and the drainpipe will not fill
permanently fill with water.
