Antennas, experiments, engineering and other articles of interest to radio folks.
Antenna patterns from a Diamond X50NA reveal how radials of proper size mitigate current running down the feedline and mounting structure.
Antennas shipping with ineffective antenna decoupling are on the rise as manufacturers daringly advocate 1/12 wave radials work.
Here are some details regarding the next, and probably last, phase of my 43 Foot DX Engineering vertical installation.
This post is very late. The actual date of the events within it are just before March 2009 in preparation for the Virginia QSO Party.
In the many posts within this site, it is no secret my examination of various vertical antenna solutions with comparison between BigIR and the 43 Foot products a big part of this. Check out all the 43 Foot posts on HHD here…
If you might be wondering if there is a difference between older and newer Radial Plate kits from DX Engineering there is… for the better, but there was a catch…
With the upcoming solar cycle pushing operations on the HF bands towards success on 20 meters to 10 meters you might be wondering if a vertical antenna may be the right choice for making the most of this time.
Well, to be honest you may well have just as much success with a simple horizontal dipole strung up.
Dipoles are pretty easy to build and don’t cost too much if you would rather purchase one from Alpha-Delta or the Wireman.
However, if you…
