MikeB: Hello Imy sorry i have looked over this site over and over and can't figure out if there is a fault or something has changed. I have an old setup in my bedroom just a simple portable tv and free view box which are both old so nothing fancy here although I do use it most days. Except the other day it all just went completely black and has not returned at all. It is sensing remote control only to put on stand by or on but no menus or other functions just black screen. Is this a fault or a change or just my own equipment. I think i did work out that I am the crystal palace one I am DA11 Gravesend. Thank you

It sounds as if your equipment has failed and possibly needs to be replaced.

Mr Thompson:

You say you have two dishes. Have you got planning permission to have two fitted? See Planning Permission: Houses and buildings up to 15 metres high | Satellite,TV and radio antenna | Planning Portal for details. If you already have an aerial and a single dish, you are required to obtain permission for a second dish.

If you do not have permission, you can resolve the problem by having a quad LNB fitted to the bigger dish, assuming that is aimed at the Astra satellites parked in geostationary orbit at 28.2 and 28.5 degrees East. That has four outputs so can feed two satellite PVRs at once. If you need morefeeds then an octal LNB would serve.

I concur with MikeB that you need a 'proper' aerial for your terrestrial reception. A good log-periodic is advised as that will cover all current and planned future channel usage. Never buy one that is too small, it is better to have a higher gain aerial and if that gives too much signal you can reduce it with an attenuator if needed

MikeP: thank you. I suspect need new equipment the only thing I wasn't sure is that when I click on the map showing freeview map it has green all around apart from some grey patches and I am in a grey patch so just thought it might be that before I buy something new. Thanks
