Comparing Elevated 1/4w Vertical vs. Link Dipole with WSPR

Rudy Severns is the king of elevated radials.... a great read.

Here is what you might gain from going from 1 to more elevated radials. For great results, it seems no fewer than 4 radials of slightly longer than 1/4 wavelength (or about .30 wavelength long) raised 4 feet off the ground at center, and about a foot off ground at ends is something to shoot for. Eight raised radials are better, but that's a lot of work for a portable set-up.

The pattern improves with more raised radials, but not a lot of db improvement:




Owen Duffy also has some great comparison information on radials:

I really love reading this stuff....

 

I've gotten quite a few requests to run this test differently next time...

I'll certainly add more radials, and try to get a bit more separation between the two antennas. Lots was learned with this experiment.

Thank you everyone for your input, what a learning experience! - I've received numerous emails from folks and their experience with similar setups, and how to try things a bit differently next time!

I'll be using this Vertical antenna for a Parks on the Air Activation with N9MM & W5MIG on December 10, 2017 - so lookout for us on the air & give us an honest signal report!
