In most cases it's the analogue channels which cause the problems, as they are normally significantly stronger.

My System: Dreambox DM7020, Orbital 1m Dish, MTi 0.2dB Twin lnb, Technomate SG2200 motor. Rover DM16C Digimax & Rover DL4 Meters.

The analogue channels are usually 20-25dB stronger than the Digital Muxs although they do have a tendency to be at leat 3-4 channel frequencies away from the digital stuff.

The problems with Digital is that its not all about out and out power as it is with analogue, its all to do with the quality of the signal. As long as the Digital output is around 35-40dB it can be launched onto a communal TV system without too many problems

At work we normally try to launch the analogue stuff at about 80dB and the Digital muxes at about 55-60dB

The biggest problem we usually have is co-channel interference from one of the digital muxs effecting analogue channel 5, but only off one transmitter.

Strange that one. I suppose if you overlap the transmitters footprint that would happen. I was just reffering to individual transmitters in my area, all five of them

A fairly annoying issue has cropped up

Them bunched in with Ch5 ....... Bit of a pain that ..... Any thoughts/suggestions ?

Freeview is on Vertical polarisation, so you will have to go up on the roof again

But before you do that, Five transmits on half power at Pendle Forest and so it is always going to be difficult to obtain with the same degree of reliability.

http://www.ukfree.tv/txdetail.php?a=SD825384

Try swapping over the attenuator for 18dB (or 18+3) and rescan. You may find the original selection was possibly a bit too severe for the higher frequencies (especially when it gets cloudy).

Well, Winter Hill is horizontal. Presumably your aerial is set up for H trasmissions?

Well scrap the last theory then, all muxes are on the same power.

Is it a group C/D aerial ?

No wonder Analogue Five's still unobtainable on my little loop aerial...

A little fact, back when Five was first testing and after it launched (I remember that Spice Girls video, I just wish my VCR could record!!!), I was the only person in the house to be able to get it from Pendle Forest (through the use of 2x boosters on a Labgear indoor aerial)!!!
