A couple of thoughts...
5 clip-on ferrites is extremely insufficient at 160m, get some small
diameter coax and large toroid core for decoupling.

Set up your beverages as reversible. The ability to switch between
I think the first question is - whats you steady noise level with your TX
antenna? Maybe S5 is a 30db improvement. If not, in my experience - steady
state noise is either a local point source close to the antenna (is there
anything along the path or within a few hundred feet of the end? Houses,
Hi Lee,
The only thing I've noticed are some pops going on some of the receive antennas
that I think may be an electric fence or some power line arcing. They are about
1-2 seconds apart. I see them sometimes and I can see it causing the AGC on
fast to cut back the gain on the receiver. But
Hello All,
I may not have seen all of the posts on this topic but will comment anyway.
Two things come to mind about this noise. Number one is you do not want to
connect the shield of the coax going to the receiver to the ground stake for

Yup. I get emails all the time from people doing just that (I wish they
would ask their Beverage antenna questions here! :-)
Think of a rotatable 20m beam, on a tower and with a rotor. *You have to
point that towards the DX. And the same is true of a Beverage*, phased

Hi Mike and the group,
Oh, the reason the antenna is going to the north is that it's the most
convinenant direction to run my first beverage. I also tried some RG-11 (also
scrap from some CATV company I think) as a BOG. It's about 170 feet (that's
what I had) and I used it to just check and
Hi Terry,
Is there a reason why you're pointing north? That's the wrong direction for
Aruba, especially with the very narrow beamwidth it has on 20m! :-)
On my Beverage antenna page at
www.w0btu.com/Beverage_antennas.html near the bottom, is an explanation of
where we should point our Beverages.
Hi folks,
I put up my first beverage recently. It's about 550-600 feet of 17 gauge
electric fence wire running to the north about 6-7 feet high. Not terminated
right now but using a beverage transformer I purchased on qth.com and have not
