Yes, it's a ground plane type, but what band/frequency usage?

The description of the item gives it away a bit. It says...

"Outdoor FM Radio Antenna". Possibly 88-108MHz?

0/10 for observation

Hehe, but the guy who is selling does not know if the description is
correct.

Hi Richard,

Consider, if you could accumulate half a dozen of these you could then
build your own phased array to take care of your interference (some).

Yea! :c)

No, what I decided was that I needed to use phase nullinhg/cancelation, I
mean adjusting the phase and amplitude of the undesired local signal (got
from a dipole or omnidirectional antenna) and combining it with the
intefering signal from a directional beam. Which is a different tack than
nulling out using nulls in antenna lobe patterns.

I could so with an FM omnidirectional antenna, but the one that is on ebay,
I don't think it is an FM antenna, despite the description. Looks possibly
a scanner type. But, I don't know.

Rich.

Well, I'm off to bed.

I'm hoping that when I awake in 7 or 8 hours time someone will have posted
their opinion on what band(s) the antenna might reasonably cover. The seller
does not really know if it's an FM (87.5 - 108Mhz) antenna.

See ya!!

I'm going to the land of nod.
