Spacing for power handling right. I believe 6 inch was used because of long distant runs say 300 feet or more. To the antennas back in the horse and buggy days, I mean Model T days. They used High im

I followed the steps. I kept speaking into the mic and turned down the power drive on the OMNI VI Plus until the OVERDRIVE led on the Hercules II stopped popping on. That point was 300 watts out on S

I am just using the RF Output LEDs on The Hercules II. Does not really matter, it is not MAX output thats for sure. Instantaneous spikes are being cut off at the 300 watt mark and no OVERDRIVE. Keep

If you take RG400 or RG213 or what ever for each piece of coax short the center conductor and shield together on each end. Space the two pieces about 1/8 inch or just tie wrap them together and you h

RG400 is like RG58 on steroids. Too small OD for my suggestion. For 200 ohms you would need RG8, RG213, 9913 and the sort. Keep The Faith, Jim K9TF/WA9YSD ____________________________________________

So with the 250 watt element, +-5% Full scale so at 150 to 250watts full scale +-12.5 watts, 50 to 150watts so at that spot it would be +-7.5 watts and 0-50watts it would be +-2.5 watts all with the

This is interesting, 1:1 is 10w 2:1 is 5w, 3:1 is 2.5w and 4:1 is 1.25w mismatch that radiates from the antenna if you just use ratios. So some where in between is what is actually happening. Where d
