Power Usage
Dear All,
I have been having very mixed results this summer despite being 400 feet above sea level with uninterrupted views of the sea in my QTH in southern Europe. I use a half wave dipole. My experience seems to range from 9 +30 to not being hear at all especially into Southern America.
Does anyone have firm information on the use of high power by stations ? I am wondering if this is why I can't be heard ? I also noticed the same stations seem to be working the world day in / day out particularly in the US. Any insight / info would be gratefully received.
Thank you.

Re: Power Usage
Hi there, what aerial are you using? Not as many stations using high power as you would think, but the antenna is the key

Re: Power Usage
A lot of the "big guns" use directional antennas like yagis or quads.
If you can't run one try upgrading you dipole to a 5/8 vertical which will have a little more gain but lower angle of radiation for DX working.
Power is not the thing. Save your money & upgrade your antenna.
I hope this helps.

Re: Power Usage
Also what coax are you using?

Re: Power Usage
Hiya balacleigh.
As 26dt630 and yamanx1 was saying the antenna is the key more important than lots of power. 5/8 vertical would be good. I use a home made slimjim very cheap and easy to build with a low takeoff angle around 6-8 degrees Iv spoken to several south american counteries, australia south africa on 20-40 wats when the conditions where good without any problem also indonisea and papa new Guinea.
It is fedd with coax but I am thinking of feeding it with twinfeeder the antenna is about 60 feet asl and 30 yards from the sea
