Various Active Antennas

In response to a request for help with active antennas posted on the GQRP list. Chris Trask N7ZWY / WDX3HLB posted the following interesting response:

"Here is a design for an active short monopole:

a remotely tuned ferrite rod:

an active wideband dipole:

a remotely tuned loop:

and an indoor loop:

I'm working on an indoor loop that uses a dual 365-pf variable rather than varactors.  It will have higher Q and zero overload problems."

So a few projects to keep people busy over Christmas and SWL QRV.
