Has anyone tried feeding an aerial amp into an aerial amp?
Does it cause noise probs?

I have 1 aerial skt in the house, by the tv. I can cut that in the loft
and feed it into an amp, then dis it to other rooms, no prob, cept I need
3 feeds by the tv. I could -
1 - Provide 2 more drops, PITA
2 - Add another amp ??
3 - Would a 3 way splitter work? Suck it and see I suppose.

Any info gratefully received.


Why would you need 3 outlets by one TV ! You can add a distribution
amp to overcome cable losses and to provide more outlets. If you want
to, you can use a VHF dipole which is perfect for 88-108 and DAB,
then plug that in to the amp in the loft with the TV aerial. Get one that
takes a VHF and UHF input. Then the outputs will be combined VHF
and UHF. Split them in the various rooms using a diplexer between
tuners/stereos/DAB and the TV equipment.
Very easy to do. I have one aerial for 88-108MHz and a TV aerial.
That provides coverage of 88-108MHz, DAB and UHF TV. Two cables
are fed in to a distribution amp. Various cables are run to different
rooms.
The longest cable is 60ft, so over half the signal is lost. At the end of
it I
have a preamp. One cable to the TV, one to a DAB radio and another
to a normal radio. It works perfectly well. No signal overload or noise.
I get DAB from 60miles away on one multiplex in good weather. No
problems with the nearest TV transmitter 25miles away.
Splitters are not recommended unless you have a very strong signal as
they attenuate the signal badly. 3dB is half gone, 6dB is going to leave
a quarter. Put them in series and you might as well unplug the aerial.
