Getting both Channel Island and French TV channels

[formula_86]

Say if you live somewhere on the Channel Islands region, and you buy either an IDTV, a box or recoder with DVB-T2 Freeview HD, is it possible and practical to diplex two aerials into one so that you can recieve all 18 channels from Fremont transmitter + all the unencrypted French TV channels?

Furthermore, would a DVB-T2 reciever be backwards compatible with French terrestrial HDTV (which uses the older DVB-T MPEG-4 standard rather than our newer DVB-T2)?

it would work yes as you can pick up different regions on Freeview if you can get both signals.

as for your second question no DVB-T2 & DVB-T MPEG-4 aint compatible with each other, some receivers do support both but many dont & you'l have to check when buying one to make sure that it does

No a diplexer would not work if the frequencies are the same not unless you use a switch instead of a diplexer. What you need is a twin module receiver (don;t confuse it with a twin tuner) that will be able to scan both modules independantly (they tend to have options like DVB-t/DVB-s and DVB-C modules) but they are exspensive

Only other option is two individual boxes (should be cheap in each country or off ebay)
