Hello Lee;

 

Great to hear from you.

 

Yes – I have a pair of VE3DO loops – spaced 5/8 wave length – aimed at Europe 
(also can be switched to 225). Then a single VE3DO loop for 135/315 degrees. It 
is all about more choices. I have a HI-Z 8 circle and a HI-Z 4 square – also 
spaced 500 feet apart – broadside on Europe.

There is a 5 element parasitic vertical Yagi for 160 that we use for TX and RX 
– that has tremendous F/B (for 15 KHz of the band). This was published in the 
Yagi chapter of the last three editions of the Low Band DXing book.

So 3 main sets of RX antennas. Any two of these RX antenna arrays can be fed to 
the DX Engineering NCC-2 for antenna combining to develop incredible directive 
patterns.

 

Beverages need to be away from towers and other antennas to work well. I just 
cannot get them far enough away on this property to work – so they are gone. 
The short vertical arrays work great. Twice we have worked over 100 countries 
in a weekend on 160 meters with this setup.

 

I am 1 mile from Ohio J

So you're using the VE3DO loops to augment the Hi-Z and tx antenna - just to 
have more choices?  Presumably the loops are better at some times than the 
other choices, correct?

 

And, the Hi-Z circle arrays are generally considered better than Beverages 
these days, aren't they?  I'm surprised you don't have Beverages....

Greg, W8WWV has done some new work on the VE3DO loop.

I use 3 of them here at K3LR.

Greg's latest paper is here:
