Greetings All, I've been looking into active RX antenna arrays for receive only low band operation. Interested in the DX Engineering type ( DXE-ARAV2-4P ) with (DXE- RFS-2P) in 4 square configuration
Guys, Thanks to all those who responded to my question about the active antennas and arrays of the same. I started responding but did not realize that there were so many posts that I could write all
Bob I am constructing a DXE style receive 4 square using shortened verticals with ICE 135B preamps for each active antenna. I will use a small choke and resistor is series at each preamp to impedance
verticals with ICE 135B preamps for each active antenna. I will use a small choke and resistor is series at each preamp to impedance match the short vertical to the preamp input at 1.8 Mhz. I will al
These short vertical RX arrays look really interesting. I'm wondering if anyone is using a 2 element end-fire version! I have room for a 2 element array here running NE/SW. It would also be 90-100 ft
Assuming the technology of the K7JTR 4 sq controller is the same as his 8 antenna design it is a single band design where the DXE (W8JI) controller uses crossfire phasing which works on both 160 and
Bad assumption Joe. "This unit was optimized for the 160 meter amateur band but can be used from below the broadcast band to over 30MHz." http://www.hizantennas.com/controller_4_elements.htm Before s
That still doesn't answer the question. The 8 element design could be used on any band but the phasing was such that it was correct only over a narrow band. The W8JI "crossfire" design hold the phas
Please carefully read Lee's description (asterisks added): "This controller was designed to connect 4 shortened antennas using Hi-Z amplifiers into a directional receiving antenna. This new and uniqu
It's been interesting to see the reviival of interest in the four square veritcal RX arrays. I built, I believe, the first short vertical RX array based on the original W8JI design back about a deca
Yes, the time delay phasing (crossfire) has been disclosed for a very long time on Toms website. There is more than one way to accomplish phase tracking with a 4 element array. I cite Rick N6RK and h

Hello Joe, I appreciated your post. You said that "The "phasing" part of the W8JI design was on Tom's web site for a very long time." Sounds like it isn't there any more; do you have a copy of it, or
