Hello Dick

I have good results with my vert antenna and insulators at
12 meters high, the top load is a 13 meter cylinder 1.5 meter
diameter made from galvanised wire cap is abt 350 pf
Look at the gallery of G3YXM to see the antenna
Best 73 to all

Hello all!

I just finished and tested the powersupply that should power
my 136kHz station.

50V/16Amp continue without any problem.

That 16Amp is the point where I set the current protection,
but the transformer is a 1000VA type.......

Most transmitter components are here, but waiting for just a few
difficult parts.

Meanwhile I'm thinking of what kind of antenna I will use.

I am planning to take down all my VHF-antennas from my old tower,
and extend the tower up to 20 meters.
The tower is ungrounded, but it does stands in concrete.
I want to put up some kind of isolated toploading with 'pancake-coil'
and some short wires (like EI0CF did in the past), and then feed
this by a single thick wire, well isolated and some meters away of the
tower.
This sounds nice, but I have really no idea what influence the metal
tower will have on the performance.
It isn't directly grounded, but I suppose there will be some leakage in
the
concrete.

Anyone with experience on this around?

73, Dick, pa4vhf
