i will put the coax choke inline today. In virtually every installation I've used one it helped to produce a wider, smoother SWR curve for me, too.
I have another larger plastic disc I can use here, but I have to measure it to see if it is larger enough to get above the dog bone. If not, I'll have to fabricate the item somehow.
The only changes I measured between were the diameter of the radial ring and placement of the radials at exact quarters of the ring circumference, and the length of the gamma rod and lowering of the gamma sleeve to equal elevation with the mount points of the radials.
Taking the antenna up and down so often caused the four radials to skewer out or equal placement along the ring circumference. Straightening them out brought the SWR down to where it is, but higher into the freeband than I wanted. When I discovered moving the dog bone up along the gamma rod and center radial moved the center of the SWR curve down, but extending the rod screwed it up, I decided to try a longer rod that could sit inside the gamma sleeve as it was but give me more room to take the dog bone higher up the radiator, this drove the low point of the SWR down the band, I I had a longer gamma rod I'd see what could happen next. I can only surmise that the open cage ball on op I don't have has some effect on electrical length my straight shaft doesn't. Do you think a cross wire hat would help.
Yes. The Qv4k is better than the sleeve now in the same way as it was the other way around before. I am anxious to get it higher now.
Are you kidding? This has been a forum wide community project. We've done this together, but I get to play with the antenna.
