I have a UHF audio-video sender unit which I am attempting to use in a house with three floors, in a remote area. The aim being to send the signal from a VCR downstairs in order that a couple of TVs on the upper floors can receive it.
Thsi is the device I bought:
In actual fact it is smaller than it appears - about half to three quarters the size of a VHS cassette.
Anyway, it works surprisingly well on the whole, but the signal does not reach the uppermost floor with enough gain. So I'd like to amplify it a bit more (no more then 50% I suppose), or otherwise increase the range.
So far I can see two potential ways:
1- use a larger aerial than the small telescopic rod antenna fitted. (not sure if the sender's o/p electronics would be up to the job though)- Connect an amplifier in series between the output of the sender and it's antenna.
There may be simpler ways; I'm all ears.
In regard to (2.), I was thinking of adapting a TV signal booster amplifier with a 20% variable gain I have lying about. Not sure at what part of the sender's circuit I would need to attach it though (I don't have the schematic). Presumably it would have some effect if I connected the sender's rod antenna terminal to its input and then connected another antenna to its TV output jack .
Any thoughts? Thanks
