Hi, Carsten
You might try it with just a series C into the 3/8 wave on 80m. The VSWR may
not be that bad! Then you could always add a 4:1 balun or transformer if
needed.

Subject: Topband: impedance of 3/8 radiator and question on matching
Hi,
I am playing with a 3/8 radiator for 80m (to the time being fed against
40 radials of each 40m length).
What is the impedance I should expect from a 3/8 radiator?
My plan was to use it as a 3/8 on 80m and match it for you on 160m too
(until we will put a Gamma match on our 60m tower).
Here is what I measured with my AIM today:

(and here the actual *.SCN file):

Any advise on matching would be welcome ;-)
Thanks!
Carsten, DL6LAU
