Now in the most recent 22nd Edition of the ARRL Antenna Book...
3-14 - It goes on to say that a few elevated radials should perform as well as
a large number of ground radials
And that the signal will improve quickly with just a little elevation...
Interesting graph - Figure 3.27 - you ne
There is some good stuff in ON4UN Low Band Book - Chapter 9-10 on Elevated
Radials.
He suggests that an elevated system would be even better above ground versus on
the ground in poor conditions. References 0.1 wave height or less. For 160m
that could be 50 feet down. In Section 2.2.7 K3L
I can't believe that no one has put this really important question to bed
already.
If I had the land and an existing vertical with a large buried radial system
and another tower available.. I would try it out for the sake of Ham Radio :-))
Put up another 160M vertical.. contact a few friends
Roger...
As a new ham operator (1 year now).. I'm impressed by ARRL and what they do.
The publications, the website and licensing information and support. The fair
cost of membership, the speed of package deliver to Hawaii, email response.
The only thing I can complain about is the backlog
You can go to the link below to see current status.
They are about 10 days behind. They posted a notice saying they are upgrading
the system.. perhaps 5-7 weeks now.
Today, technology is cheap and fast so they shouldn't have a problem once they
put the right equipment in.. 9 million QSOs to
Hello,
Your location sounds similar to mine. I'm on a hill about 200 ft up and about
100-150 yards from ocean.
I figured I'd throw yet another dipole over the tallest tree behind me. It's
only about 30ft off the ground at the center - right next to the 40 and 80M...
The 160M ends are
Mike (KH6ND) at KH7X is a nice guy. He's operating at the North Shore on Oahu
at a great Ham Radio QTH.Towers.. On a mountain.. Ocean...
He holds many records. Traveled all over on expeditions..
I was fortunate to met him through my elmer (KH6R). Helped him move recently,
and he gave m
I got my first confirmation that the low dipole is working and not just
transmitting straight up into the air..
Last night my Elmer came over to play around with the CQ CW...
Around 11PM Hawaii Time or 09:00 UTC...
He worked 18 stations in one hour. (I'm in the process of learning CW). Al
I did a search for K2UO here and didn't see anything recent, so I thought I
would post the article again for those with Low Dipoles or tight spaces.
Mentioned in ON4UN's book.

Yes, I didn't get that right and makes sense. Only 50W on my Radio.. 1/2
power into Amp.
I'm obviously not electronically edumacated (as they say in Hawaii :-).. just
trying to figure out how to reach out without spending an arm/leg or hurting
anything :-)
I ordered the Array AS-RXFEB to t
Thanks for input.
Because I'm using two different radios for TX / RX - This product from Array
sounds like a simple fix to RF overload.
I think if I was using one radio and needed to switch - I'd go with the other
products.
I guess I'll see about any volume? issues with that setup?Do my o
Thanks guys.
It sounds like the DX and MFJ are out because of Watt limitations (200W?).
There are two Front End Savers so far..
KD9SV Front End Saver and OK1RR Saver
And there's this.. which sounds simple if I want to use my Yaesu 987 for the
Beverage RX only. No changes to main rig config
The DX switch only handles 200 watts and the MFJ is about the same.
Being as popular as 800+ watts is for 160 with two antennas tx rx there must be
more I would think?
I need to check manual. Do transceivers config for auto setup and switching
with antennas now? How to handle input power of
I need to figure out what's the best way to connect a beverage antenna for RX
and my dipole for TX.
I have a TS-570 and I can use the Antenna 1 & 2 connection - but then I'd need
to manually remember to switch when transmitting etc. don't want to damage the
beverage.
I have a Yaesu 987 that I
I don't like seeing all the comments I'm reading in the cluster reports. It's
sad.. but it will pass soon.
Like someone else pointed out.. I'd hate to see people turn away from all the
hassles of an expedition like PT0S because of the acts of some.
I haven't had contact with PT0S yet but I k
I'll look into the chicken wire. I heard about that. That sounds good. I
should be able to run it to the right and left of the terminated end. Stick a
piece of copper in the ground too.. some wires.. a few long ones... :-)
On the feed line I can use some of the same, just not as much is n
I was just reading about SALT spray in Hawaii and the what it does to the
soil.. I never thought about that. Salt spray and not much rain for me.
Salty volcanic top soil/rock?
Again, thanks for all the emails.Helped walk it through.
Going N/E and taking it as far away from Dipoles as
Thanks for the input guys. Very helpful. I guess those emails don't show up
here (private)? New to this system.
Forget what I said about dipole radiating right off the ends of the line -
straight out.. I thought I read that in one of my books and it said that most
people didn't know that..
Tonight right after sunset I heard AA0RS in Colorado for sure. He popped up on
the cluster right then. (I need to learn CW).
He was 5-5 on LSB but only 5-1 on CW. I was surprised I couldn't hear him
that strong on CW because he was loud and clear on LSB. That's pretty unusual?
I believe I
After some more reading... It looks like NE is the best approach. Point it
towards North America. I can probably get it pointed at the lower states.
I wasn't sure if I wanted to go bi-directional or not and try and get Australia
/ NZ but I think I'll go for quiet and just try NA for now.
I
This is my first post so I hope this is correct. Not sure where it's going..
how it's linked in the thread?
I have a 160M dipole up as high as I can. About 40 feet at center and 20 feet
at ends in the trees. On a sloping hill.. 200ft above ocean that is <100
yards away. South and East are
