[TowerTalk] Using 75 Ohm Hardline

[Don Havlicek]

Your tuner/transmitter/amplifier will not know you're using 75 ohm 
feedline IF you tune the output FOR 75 ohms impedance.
As for the antenna ... if you adjust the feedpoint match ... you can 
MAKE it a 75 ohm antenna and feed it directly with the hardline.
Why are WE, the hams, so hung-up on making everything 50 ohms impedance?
Those 50:75 ohm transformers are generally a waste of time.
If you think this isn't a possibility, make a 75 ohm dummy load and tune 
into it.  You'll need a 75 ohm SWR meter [does bird make a 75 ohm 
wattmeter?] and you will find you CAN tune your amp/rig/tuner for a 75 
ohm load.
Just my 2 kopeks.

> Hi everyone. I was wondering if someone could recommend an easy and elegant method that would allow me to use a bunch of 7/8" 75 ohm hardline I have.  My antennas on 2 of 3 towers require over 270' runs and I would like to use this very nice hardline.  On VHF and UHF I built custom 1/4 wave transformers which have worked perfect for years but for my tribander that approach will obviously not work.  Any ideas?
