I'm installing a full-size ground mounted 1/4 wave vertical. I mounted the
vertical on a 5' pipe. The vertical is insulated from the mast pipe using a
base from an old Hustler 4BTV vertical. I will now get to work on the ground
Question: With the full-size ground mounted vertical connected only to the
5' mounting pipe, no radials, I thought I'd see what the SWR and impedance is.
I was expecting a low impedance of about 10 ohms. (poor ground = low
impedance = low performance)
However, using a MFJ-259B at the input of the antenna the impedance, at
resonant freq. is 100 ohms. (SWR over 2:1 as would be expected at 100 ohms).
I'll install the ground radials next... but the above doesn't seem right.
All thoughts appreciated!
