Well, in your previous post you stated that "You will hardly notice any loss..." That implies that one WILL notice... Loser! You should quote correctly -not destroying the content- 'tard. A 50 ohm AirComm-plus cable costs three times as much as a lowloss 75 ohm TV-cable with the same loss. And it gives pretty much the same results -if not better- on a broadband antenna like a discone on consumer grade VHF/UHF-receivers wich do not have a straight 50-ohm impedance. In most cases it varies between 30 and 150 ohms depending on the frequency you are receiving. So there is a good chance a 75 ohm cable works even better than a 50 ohm cable with the same loss. In worst case you will have an impedance mismatch loss of 3dB, but in most cases you will have a 3dB win depending on the scanner you are using and frequency you are receiving. There are few scannists who would buy or can afford a 0,70 US$/ft cable for a 100ft run. So a good (lowloss!) TV-cable is really worth a try. Shove it, NAZI boy! dxAce Michigan USA |
