|THE SLIM JIM ANTENNA FOR 2 METERS
These are Pictures of my recent 2 meter "SLIM JIM" antenna.
The SLIM JIM is like a J-POLE that has a 1/2 wave element that folds back from
the top down.
This antenna boasts a gain to the horizon of 6db, and needs no ground radials.
from the reading I have done it needs to be kept at least 1/4 wavelength distance
from any metal, including a tower or mounting hardware. (best mounted IN or ON PVC pipe).
I will post more pictures when I get more data in on this antenna
I have given thought to making this 2 full wavelengths long (folded in half of course, with the matching section on the bottom) I.E. 4 X 1/2 wave sections long.
I believe if you stay with even mulitiples of half waves this will work. (Follow the links below to see how the project turned out) In so doing I think it will have more gain on 2 meters.
Has anyone ever built a kritter like this? Email me!
any input? Email Bryan
