HI Mike; I am glad you asked. I do know what is happening and will share here. We are redesigned the outdoor enclosures for many HI-Z products to make them better for outside use. There will be a tim
Hello Mark Yes, they are galvanically isolated. 73 Tim K3LR Does AVA-3 galvanically isolate the coaxial and power shield grounds from the ground input post next to the antenna input? Mark Connelly, W
Greg, W8WWV has done some new work on the VE3DO loop. I use 3 of them here at K3LR. Greg's latest paper is here: http://www.k3lr.com/engineering/VE3DO/OptimizedDOLoop.pdf 73 Tim K3LR ________________
Hello Ed There is very little interaction between nearby loops. We are studying interlaced loops that are 90 degrees to each other for four azimuth coverage. I would keep the loops at least 25 feet a
Hello Jim; Yes, encouraging the VE3DO loop for others to try. It has great performance for a small antenna (low cost) on 160 meters as you know. I have used the VE3DO loop here for over 20 years and
Hello Mike; There are a few different "receiver guards" out there. If your receiver guard is a RG5000HD from DX Engineering, you should be OK. As a test, I have put as much as 25 watts into the RG500
Hello Wes; The VE3DO loop has a much better front to back ratio compared to a K9AY. The K9AY is easier to erect 73 Tim K3LR From: Wes Stewart [mailto:n7ws@yahoo.com] Sent: Wednesday, October 2, 2024
Here is a great high common mode impedance choke that I use just as George explains. At the beginning and end of the feedline to all RX antennas. https://www.dxengineering.com/parts/dxe-rxfc-75 73 Ti
Hello Lee; Great to hear from you. Yes I have a pair of VE3DO loops spaced 5/8 wave length aimed at Europe (also can be switched to 225). Then a single VE3DO loop for 135/315 degrees. It is all about
Hello Mike; I use this preamp in the shack - at the end of the 50 ohm Heliax that feeds my RX antennas (very low loss): https://www.dxengineering.com/parts/dxe-z10046b-pm I also match my 75 ohm RX an
Hello John; The short verticals (I use 23 feet) used for RX only - are not resonant, so they are not nearly as affected as full size (1/4 wavelength) verticals. There is some concern with "active" ve
There are great low band antenna suggestions and options explained over the years by Frank, W3LPL during Contest University. You can access Frank's excellent presentations here: https://www.contestun
The transformer and the resister are very close together. The bottom is 40 feet long - split to feed. I tie to two ground rods. I have no experience with the other questions. 73 Tim K3LR I have a few
