I noticed you had nothing to say when I gave you the link to the page

Why have you suddenly gone quiet after saying I was wrong about it? Is
it because yet again, it has been illustrated that it is in fact you who
knows **** all? Have you not noticed the pattern yet, Adrian? Every time
you claim I'm wrong, evidence is proven to show you up as a fool.
Instead of saying I'm wrong about a subject you know nothing about,
stick to what you know which, IMO, is **** all.

is there a flat or smaller bore cable I can use for my two sky LNB
cables?

There's shotgun cable http://www.satcure.co.uk/accs/page8.htm#WF100twinCUT
but it still won't be discrete.

Senders are available. An example is here
http://www.maplin.co.uk/Module.aspx?...299&T=M odule
cheaper/better options are available.

thanks folks
unfortunately its the party wall with no cavity,
I opted for plastic square cable channel (self adhesive) running on top of
the skirting board
its not too bad, I'll not notice it in a few weeks I'm sure.

Several years ago, I saw a product that might provide a virtually
invisible solution to your problem. It is a skirting board
"cap", which has a similar profile to a standard skirting board.
Basically, the "cap" fits over your existing skirting board and
because it is slightly larger, you can use the gap as a channel
for the wires. For best results, you would probably have to
cover all of the skirting boards in the room.

I searched the Internet today and found some items at
http://www.kentsdirect.com/selfbuild...d-systems.html.
However, these products are quite expensive.

Maplin also sell a product that might be suitable. See

6.25" cable (well, pipe actually) is a standard cable used in
the
TV industry and is currently being installed for DTTV at Emley
Moor. Emley uses the same on analogue and only puts 50KW up
the

Before anyone says anything, 2x25KW Klystrons feeding 13dB of
aerial gain (=1MW) less the loss in about 500m of cable,
sorry,
pipe.


The guy who taught us antennas and feeders at my Amateur Radio
Club is a former ITV engineer who used to work on that stuff.

Mate of mine runs his own repeaters for PMR. The stuff he uses
is about 2" in diameter and as hard as hell to work with. A 30m
length of it costs £1k. Keeps telling me I should be using it
instead of RG8 and RG213.

2" OD would be LDF7-50 (or maybe FHJ7-50) which has a bending
radius of 8ft!! Not the thing to really be using for PMR albeit
with little loss irrespective of (PMR) frequency!

Are you sure it is not LDF4-50 which is very common in the PMR
business? From memory about 5/8" OD.

LDF7-50. Definitely that size outer diameter. He uses it on radio towers
he runs repeaters on so an 8ft bending radius isn't an issue as it
basically comes from antenna to container housing the gear.

What is an issue is the losses "consumer grade" co-ax has on a 30 metre
run at lowband VHF frequencies.

If your friend is using LDF7 at lo-band for a 30m run I am glad I
am not one of his customers as he doesn't know what he is doing.
The difference in loss at lo-band on a 30m run between LDF2,
LDF4, and LDF7 is not worth talking about - less than 1dB in all
cases. Even 30m of RG214 is little more than that. If we were
talking UHF and 60m run them perhaps it is worth considering but
not down there. Even Orange and T-Mobile at 1800MHz with runs of
40m+ only use LDF5!

I've been in mobile radio for over 40 years and in all that time
I have only known use of LDF7 once - when we put an aerial on UHF
at 420ft on Winter Hill with a ground run of about 25m. There was
probably as much loss in the tail from the end of the feed to the
kit (about 5m) as there was in the main run!

Who mentioned LDF2,4 and RG214? You. And the reason he uses LDF7 is
because of the price he got it for.

You may have been in mobile radio for 40 years but there's a ****load of
difference from installing CBs and taxi radios in cars to setting up a
repeater. And you even confirm you've used it on a repeater yourself.

And if its overkill, how come virtually every single provider on one
tower he bought had used it?

Stick to putting radios in taxis and leave the real stuff to people who
know what they're on about.

I think your sign-off says it all.

Did I say anything about CB, taxis, or especially repeaters? As
for the aerial on WH it was for - shall we say - a 'security'
organisation with government connections and was most definitely
not a repeater. Actually the fact that you use the term repeater
indicates just how much YOU know as, apart from Community
Repeaters (which are a specific function,) the term 'repeater' is
almost never used in PMR in the UK.

I started with the largest PMR company in the UK (manufacturer)
as a trainee and have worked in all sorts of areas of mobile
comms ever since - data, quasi-sync, scanning systems, emegency
services, fuel and power, chemicals, transport, etc etc. I am
employed by, shall we say, a very large comms organisation, so
maybe I DO know a bit more about it than your mate.

Given the price of connectors for LDF7 I would guess he is either
mad to use it for 30m at lo-band or he got it for free. Using
LDF7 - for that matter anything bigger than LDF2 - at lo-band is
just a waste of time and money. If as you say everyone on one
tower has used it then either its a very tall tower or you are
mistaken over the type of cable.

Conversation/thread ended - for me.
