Performance difference between 1/2 wave and 5/8 wave vertica

Post by Guest on Tue Dec 18, 2007 11:20 pm

I have decided to put up a slightly larger 5/8 wave vertical silver rod and wondering exactly what the theory is behind 'lower ang;e of radiation'

How much difference will this mean in terms of DX work?

Would be interested in what ppl s experiences have been on changing from a 1/2 wave to a 5/8 wave aerial on the 11 M band.

Antennas can be something of a black art.
In that just because Bod down the road gets wonderful results from his M3TB set up, it will not follow that you will.
A good site for looking at radiation patterns is

Also do not forget that antennas at the half, rather than the quarter wave will not be at 50 ohms.

Black Art Indeed

Have worked 5/8 1/2 and a99 and they were almost all working the same and the same qso were made at the same signals almost.

BLACK ART INDEED

I have decided on the same 5/8 wave silver rod at two different operating locations from 2008.

So it will be interesting to see the different results between two QTH's


Wi;; keep you posted.
