should I use 50 ohm or 75 and how long? 3/4 wv phasing lines? Found an old info sheet showing adding 1/2 50ohm coax to existing 1/4 75 ohm?? Wayne k8lee ______________________________________________
You can use either. With 1/2 WL of 50 ohm or 75 ohm cable, and impedance matches what is 1/2 WL away. When I rebuilt my 40 4 sqaure, I used 3/4 WL 75 ohm cable - saved having to splice in the extra c
Just make sure for 50ohm the .66 velocity factor leaves you enough cable to reach the antennas from the control box. de Joe aa4nn should I use 50 ohm or 75 and how long? 3/4 wv phasing lines? Found a
I don't feel qualified to answer your question. If you are not making progress you can write to my son KZ7Z. I don't fool around with coax often. I use 600 ohm open wire line with a current 4:1 bauli
FWIW I used Sat TV Cable (RG6 I think) here in the UK. Works a treat for QRO and quarter wave lines on a 40m 4 Square. Home brew switching box as well. 73 Adrian MW1LCR / GW9X On 26/08/2013 02:20, TO
