<p>A higher gain antenna will help a little , but important to have low loss coax ( rg6 or very long runs RG11 ) UHF / SAT rated low loss splitters , avoid all those loop in loop outs on boxes some seem to have several DB loss .My old Hard Drive recorder has over 6db loss on the CH 33 35 37 area going thru the antenna in Antenna out . Use a high quality splitter instead . In some cases a 20db Gain Low noise Figure amp typ 1.5db NF will make a huge difference , but watch out for…</p>

<p>Don't use too much gain or you will overload the receivers and bad MER ( quality ) will result .</p>
<p>I use a Swedish made meter measures level SNR MER and a handy bar graph showing the 4 carriers at once Igloo , Mediaworks TvNZ Kordia etc</p>
