[QUOTE="spiney, post: 192374, member: 192438"] Well, it's very difficult trying to give advice, from a different broadcasting setup in another country, but ..... It's best to use wideband metal block "satellite" combiners (in reverse) that work over 5-2400 MHz - even though you're only on terrestrial frequencies - rather than the cheaper and much worse "Y" type plastic splitters. This assumes that: 1) Your reception on each aerial is adequate to start with, ie you're within range of - and using the correct aerial for - each wanted transmitter. 2) There isn't cross-interference between unwanted channels on the different aerials, which might manifest as various "patterns" over the wanted channels (I'm assuming entirely analogue broadcasting!). When combining several aerials, this is a common problem, even in the UK with UHF only tv transmitters! If so, then you might need to fit frequency filters individually to the separate aerials, depending on what problems might be encountered. For example, you might have to fit different frequency bandpass filters separately to the VHF and UHF aerials. But, the combiner is still the 1st step, you won't know what else might need doing until you've 1st tried that! Obviously, any local help and advice you can find would be most useful! And sorry, no idea who your best local supplier might be! (For info on such splitters, see links near bottom of my Freeview aerials guide, in our FAQs section. Most of that is about UK digital terrestrial, so doesn't apply here!). [/QUOTE]
