Has anyone experienced difficulty in tuning this antenna. I have been using and antenna analyser and have horrendous difficulty in tuning the bands on it.

I have read that the reason that the antenna is horrible to tune is to two problems, one -- the coax connector at the base of the antenna has a broken center connector at the pl-259, the other affects the lower bands, ie - 30m down, the 4 similar capacitors on the pcb at the top of the antenna( that has the tap for 2-meters) needs to be replaced with 390pF that are RF rated. I have Bought some off of ebay and still waiting for delivery.
The symptoms on 75/80 and 40 is that as you get close to the resonance say at 3.950 the impedance goes up above 3:1 ...
Ill know more for sure when my capacitors show up and i install them ... im also going to try to add 160M by adding 3/4Y to the end of the loaded section.
