Indoor Groundplane
Fin and I got together and (mostly Fin) made four groundplane antennas for testing low power transceivers.
I sent two of them to Nino for work on a radio project. The other two ended up in the hands of new-hams.
I don't remember who has them.
The big thing I like about them is that they are somewhat heavy so with rubber feet they don't slide off a table or top-shelf they are placed on.
