[OZAPRS] 10.147 MHz antenna

[vk4tec at tech-software.net]

Sweet

 

My tracker is in USA and on its way 

 

What power ?

 

Should I just not use any path for HF ?

 

I am up at 2am because my eczema is playing up 

 

I am itchy and bleeding and dog tired

Hi Andrew,

 

SO239 base is mounted on approx 200 x 200 mm sheet of aluminium which is
bolted to the rack.

 

Rack is providing a counterpoise of sorts.

 

At this time rack does not have a good dc path to chassis (fibreglass canopy
in the way).

 

In process of making earthing straps using copper strips approx 25 mm wide
to remedy this.

 

Shifted antenna late yesterday and haven't redone sweep yet.

 

Should be able to get back to it tomorrow.

 

Heard by vk4mq-4 1600km so it is operational but probably not ideal

 

Regards

 

Peter
