With my TV's built-in receiver, Prime/Maori channels are good; TV1 channels are ok and TV3 channels are well below acceptable quality. I would like to get good TV1/TV3 reception so I have try my friend's amplifier today and it worked great!! It was a Kingray 2-way amplifier like this one: http://www.dse.co.nz/dse.shop/4c10eb20034c9e50273fc0a87f3b0691/Product/View/L4219
However I found that the signal gain is only 16db....
There are two other models on the DSE website:
http://www.dse.co.nz/dse.shop/4c10eb20034c9e50273fc0a87f3b0691/Product/View/L2105 with an adjustable knob and 26db UHF gain.
and this masterhead one with 32db UHF gain
How do I choose among these three? Is it possible for the signal to be too strong? Is the adjustable signal gain important? Would you recommend any other amplifiers from somewher else?
Thanks heaps in advance!!
