Subject: [TowerTalk] JK C3S WARC Modifications
<I have a C3S tribander which I seldom use except when on WARC bands. It is
<useable there but not as good as I think it would be modifying it for 24
<and 18Mhz. I wonder if anyone has tried that? I don't care about 10 and
<15. I think by just changing the dimension, i.e making the 10-meter
<elements longer for 24Mhz and the 15-meter element shorter to cover 18
<Mhz, would possibly work. Is there anyone who has done this successfully?
<Herb, KV4FZ
## contact Ken at JK ants. No need to buy a megabuck new yagi....then
ship it to KV4 Land.
The issue with the F12 els is.... the brackets for ele to boom are fixed
In place. The saving grace is the
18 + 24 mhz bands are only 100 kz wide.
## BTW, ur 15M eles would have to be made LONGER, not shorter. I would
shorten the 20M
eles..and relocate them to where the 15 els currently reside on the
boom.
## what u propose is easily doable..at zero expense.
## Then u end up with a 18 + 24 mhz duobander...with flat swr +
good gain + good FB.
