I received a number of replies to my question about RDF. Many thanks to
all. The consensus was that 2 dB difference is the magic number. Thanks
again for your interest, and I look forward to seeing all of you on
Topband.

Recently, I have been intrigued by the antenna parameter RDF. Please,
can someone tell me, by how much can RDF change(dB) before the
difference in performance of the antenna will be noticeable to the user?

Thanks to all who responded re the shunt fed tower issue, Now have it
wkg. I had amp throttled back to 600 watts this AM and got decent
report from VK3ZL.

abandoned the inverted L for
shunt feed of my tower(which many years ago, I used successfully), I
have been able to successfully match the Shunt Fed tower using a Omega
Match'
So my question is: How effective is a Shunt Fed tower, AND, is it more
effective than the Inverted L?

This is a very interesting U-tube presentation by W3LPL on solar
activity. A good portion of the discussion is about Topband.

All were very helpful, and provided information that will allow me to go

AHAA! Another who enjoyed 1957-1958. I wasn't on 6 then(lived in a

It's much more simple than that. I just tell my system not to spot
anything from W3LPL.

s well as the HL's etc. If you
haven't looked in the ON4UN Low band hand Book, there is info in there
for controlling both antennas with one controller.
With the K9AY & a lot of help from the members of this reflector, I
worked 39 new
TX
antenna(inverted L) problem was solved by putting a remotely controlled
SPST relay in the box with the matching network. That relay is between
the radiator and the matching network and is open when in RX mode.
Enjoy, you are gonna love it.

Hi Ken:
I use a butane unit that I THINK I got at Radio Shack. It works well.
You can get the butane at Wal Mart, or most "Stop & Rob" corner places.

70 you may
see better performance. I did a significant amount of reading on this
subject, and the consensus was that this number radials is near the
point of diminishing returns when you don't have the real estate to put
down a large number of full length radials.

e slide in the
insulator. That makes it easy to pull the wire taught at the open end.
it works like a champ. It also makes it easier to trim the antenna length.

Thanks to all who responded to my question about the K9AY antenna. The
consensus was that there would be little or no interaction between the
loops. I got a response from K9AY himself who also had the same opinion.
So, it's built and ready to go.
Thanks again,\.
73, Mike,
ot at
exact right angles to each other, so as to get the end of one of the
loops farther away from a chain link fence. So, the question is, will
this configuration have any serious detrimental effect on the array
performance?
Thanks & 73,
