Hi

A question about wire ...

I have constructed a 3/8 for 160 meter. I use the tower to support the
antenna. It runs 22 meter vertically and then (horisontal for 24,5 meters
(i.e. total 46.5 meter). distance from tower is 1 meter.
A the base of the antenna it is feed with a serial capacitor of 430 pF (a
330 in parallel with a 100pF : both door noob).

Ground is a combination of 4 ground rods and wire (space is limited). Best
swr @ 1860 Khz is 1:1.4. 1:2 bandwidth is app 80KHz. A noise bridse have
shown impedans around 70+j1.

Currently the wire is 1.5mm stainless steel wire.

How much would the antenna be improved if i substitute the SS wire with with
1.5mm braided copper wire?
I guess the seial capacitor would change as well ? any idea how much ?

Antennewire i use ( steel 40050 and copper: 40051):
