Thanks for Helping
I checked out that web page I understand the concept but an not sure how to apply it
I suspect that the choke is too large to be effective on the higher bands.
From the looks of the chart You may be right (13 turns 12 inch diameter)
Is the choke at the antenna or in the shack?
The choke is in the shack (about 8 feet from radio)
Total length from radio to antenna 102 feet, coax total length 125 feet RG213
elements are at 90 degree to each other, coax is 45 degrees to each element
The following is what I was able to tune, I got 40 meters to tune (Just had to work a little more
Frequency ----- SWR no tuner ----- SWR tuner
80 1:1.5 1:1
40 1:1.2 1:1
20 1:1.3 1:1
17 1:1.5 1:1
15 1:1.5 1:1
12 1:1.5 1:1.2
10 1:1.2 1:1
Looking at this none of these are bad at all
I have a piece of 4 1/4 plastic how many turns do you think? 11??
Thanks for all the help
