[hpsdr] Active Antenna

[Henry Vredegoor]

Hello All, (Rick, Phil),

Listening to the latest Teamspeak and being temporarily very restricted 
wrt. antenna's, the subject of  "Active Antenna's" in the conversation 
between Rick VE3MM / Phil VK6APH immediately caught my attention.
I studied the website of Clifton Laboratories and found a lot of 
interesting info on it.
I  already was thinking about building a design something like described in:

http://home.earthlink.net/~christrask/Complementary%20Push-Pull%20Amplifiers.pdf

Looks similar wrt. output stage, input stage is different.
The design by CL looks a lot more robust and tweaked HF wise though.
Unfortunately Jack currently doesn't sell the active antenna as a board 
+ parts kit, the kit as offered is too expensive for me.
Would be interested in the results in combination with Mercury.


73's,

Henry.
