Re: [Elecraft] RX antenna (K3)
DX Eng makes good stuff, Adriano, and I would think this to be a good vertical active whip. You might want to also check out the active whip from Clifton Labs. It is also a high quality unit with good overload characteristics and ability to automatically turn off during Xmit periods. Available as a kit and much less expensive than the DX Eng, even with the coax DC coupling unit. I have one 50 ft away from my xmit antennas at 100 W and have no problem. Another possibility you might want to explore is a K9AY loop array, even if not full size. This will give you the advantages of less RX noise than an active whip and significant selectable directionality on the low bands. I use one of these also and prefer it to the whip on 160 thru 30. They are commercially available, but can also be easily homebrewed. I use a homebrewed downsized K9AY and the active whip together as a diversity RX system with the K3. 73 Craig AC0DS __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] RX antenna (K3)
The DXE NCC1 is also a nice unit that gives the ability to adust the phase between two rx antennas. I use one with two of the clifton labs active antennas and also installed two of Jack's new HP filters in the NCC1 (It has provisions for filters but DXE decided not to build the filters). 73 Greg AB7R On Tue, Jan 11, 2011 at 7:21 AM, Craig D.

Re: [Elecraft] RX antenna (K3)
Craig I'm most interested in your system and I wonder if you could describe it further. What size is your loop and do you use a separate phasing unit before injecting the result into the K3 rx input?
