Post EAntenna 80 OCF1,5 OCF WINDOM 80m - Help?
Hi all,

I have installed the EAntenna 80 OCF1,5 OCF WINDOM 80m because the 1/3 and 2/3 configuration suits my garden position.

I have it up as far as I can get it, roughly 32 feet to the centre and have it in an inverted-V configuration with the ends about 10 ft above ground.

I have put the Antenna analyser on it and the tuning point for 80M is down to roughly 2.2 Mhz which is about 1mhz down for 80M

I am not sure which way to adjust the 80m without affecting the other frequencies as they seem to be ok.

I am not sure if this is the antennae for me as I had previously a Western HF10 that has served me well for years but got took out in the recent storm.

I am thinking of going back to the Western HF10, but before I do are there any suggestions to either get the 80m frequency correct or alternatively for a decent wire antennae that is multiband.

The OCF does seem a little deaf but I think that's because the noise floor is lower on the OCF than the Western.

Am I on the right track in my thinking? - Anyone?

I don't think there's any way to adjust one band without affecting the others, what you see is what you get. Forget the antenna analyser for the moment, does the rig have a tuner and does that handle the SWR? If the SWR is below 3:1 then the losses are going to be minimal on 80m, something in the region of 0.5dB or less depending on the length of the feeder.

Hi Paul,

yes it tunes very easily with the internal antenna tuner - no problem.

Maybe I am worrying about nothing time will tell on the OCF - thank you for the reply
