Topband: yv5mbx - Shunt Feed Problems

[Javier Remoto]

Hi,
I had been make some antenna adjustments for the ARRL Test this week-end and after the variable cap at the tower were replaced I achieve few days ago 1.2 swr in 1.830.

I was concentrated in my new Rx solution, so yesterday evening I made a whole test, but when then power achieve 1200 watts the swr goes to the infinite and beyond so I assume than the cap had arced.

I started to test with low power monitoring the swr and at 100 watts the swr were 2.0 and this number it's substained until the 500 watts level, over that level the antenna goes in short so swr goes to infinite.

I checked this morning the cap and no signs of arcing founded.

Ideas welcome!!!!

If no solution I will try to make my best at the test restricted by my conds.
