Hi Bob
Thank you for your post.In addition to the link you provided, the only
other info I have for this antenna is from

Mark,
I think you are talking about this RX antenna. I would like to know
more about it.

Hello All --
Do any of you have any experience with this antenna ?

The RF Sense MFJ type of switch box are cheap but do have limitations.
The DX-Engineering RTR-1 is a bit more money but is considerably more
user friendly with some added features like being able to check the RX
antenna vs the TX antenna either with a momentary toggle switch or with

If people were working and logging V63KS, they weren't really copying him. He's
signing V633KS. He came up out of the noise (and the noise from the east died
with the rising sun) and I worked him about 15 minutes after SR in Tucson. 579

Hello Aravind,
If phased on 160 the close spacing creates many problems for the phasing and
very low impedances.
Coax cables need to be different length than 80 meter cables.
Years ago I had phased on 80 meters, and switched to to a non phased on 160.
160 is a great band. My first contact was in Texas with 40 watts of AM on
a Viking Ranger in 1957 with a station in Kansas. I thought that was great
DX. Many years later, with over 200 countries worked, I am happy that I am
here on the East Coast in Virginia when the DX comes rolling in from
A second for the RTR-1. Well built and reliable.

I am thinking of trying a rotatable flag for 160.
I have a small lot and the farthest distance I can install the flag from
my tower is 35 feet. Since it will be rotatable I assume I can aim the

I will appreciate your advice in the best (but simple) way to switch between RX
and TX antennas for a transceiver that does not have a separate RX antenna
input.
The system should be able to switch from RX antenna to TX antenna when PTT is
applied (and vice versa) but also allow to switch

Yes, yes and yes. 9:1 transformers, beverage friendly resistors (cant
remember the exact spec) with about 1" connection to the ground rods.
Ground rods not that long but shallow clay bed here anyway and a mossy lawn

I have good luck with a pennant antenna, using a DX Engineering pre-amp at the
antenna. I live in a densely populated suburb, where it seems like every
neighbor has every RF noise-maker ever invented, and the antenna does a pretty
good job except for neighbors that are right off the front end
Hi Paul,
Glad you are ready to work DX
Are the Beverage antenna transformer and termination resistor close
to the ground rods, with short interconnect wires.?
Are your coax cables buried to help with noise pick up.?
Some of the small metal loops are not as good as the larger wire home
I Have an inv V hanging off of my 70 foot tower. Because I live on a
suburb lot the legs of the antenna are bent to fit the lot (really ugly). I
have worked DXCC (119) with that minimal antenna. It can be done but you
have to be patient.
