so your saying that broken(half there) ground plane radial
is causing the Swr's to stay high?
I am saying that your experience is typical of an impedance problem and that the missing radial could be the problem. Fix it first, then do more checking. If you have a real problem, changing coax length, or using a tuner could mask the problem

ok, going out today to look for this ground radial.
I was taking this antenna as a radio shack
super-maxim CAT NO 21-902 1/2 wave antenna
I will verify this when I take it back down and measure the
Overall Height of the Radiator!
(
Speaking of that, measure the top of the radial to the what??)
Whats making me think this is a true CLR2 is the the radio shack Ground Radials are 1 piece and i see the CLR2 and this antenna are 2 pieces at 9' which by the way the 2 sections are pressed together not screwed together like the main radiator Rods!
if it is 1/2 wave, i will add a new section to the top
bringing it to a total of 19' 10 inches..
Just wondering!( were did someone in this post come up with the extra 3/4??? i don't get it.. all i see is when i look around the internet is 9' 10".
also when i do get the 3 ground radials back up ,i am going to add a tightly strung copper wire around all 3 to cause a rejection from the bottom...will this be wise??
I mean i am going to check this anyway,just needed input on this(kind of like a rejection on a beam)..
now final Question!
is it better to tightly wrap a 10 inch coax around the mast pipe
for TVI,(grounded to the pl-259 ground on the feed coax?) (i do have 2 TVI filters i can use ,if necessary)or can i just wrap a section (like a choke at the bottom of the antenna,like 4, 6" circles then taped and hanging under the pl-259 connector)?
thanks and let me know..
Course if my coax don't come in today,. me not doing nothing yet.
Me being 45 years old and on a 30" icy roof (20F out here now)hanging on a chimney,unbolting 2 bolts that hold the 15 foot mass in place lifting the whole antenna out (while doing the lets balance it act) of the inter part of this unused chimney(theres and old water pipe coming out of it thats been there for years,don't know why but its very stable)
don't make this easy for me!!!!!!!!!
