Hi! , Bernie
I have just set up 160m inverted V(or U!) and try to work at 19:00 UTC of Jan21.
The freq. will be around 1812.5 , I am not sure to work DX as the noise level
is so high!

Bernie McClenny,
This is the title, Short Antennas for 160 Meter Radio - anyone read through it?
I have ON4UN's book from a couple of years back so wonder if there is anything
worthwhile in that ARRL version ... thank you, in advance, for thoughts..Jim

I bought it and read through it. It is a small book so it doesn't take long
to read through. Several interesting designs with EZNEC models to play with.
I could not make practical use out of any of it, ended up building an old
standard inverted L. ON4UN's book is much more useful and valuable in

Who is listed as author? That might give a clue. :)
There's a slide show (pdf file) from a tutorial presentation I've done
at Pacificon and for several local DX clubs
I think I reviewed it for our national magazine some years back. I
don't think you will find much in there that isn't in ON4UN's book.

When I first got into amateur radio, I bought a lot of different antenna
books. And every so often, I would look at new ARRL Handbooks, antenna
books, etc. After awhile, you realize that
there are only so many basic and/or practical antenna designs.
However, I did run into an antenna design that
However, I did run into an antenna design that was significantly different
(to me, anyway) last month, in an old article about inverted-Ls by L.B.
Cebik. He showed an inverted-L fed at the transition from vertical to
horizontal. Open-wire line ran down and away from it at a 45 degree angle.
Wouldn't feeding it up high in the corner like that at least eliminate the
need for radials?

I've built them for 40 and 80 via his modeling years ago. Fed both up high, and
both down low. High feed 'seemed better', but no real way to tell. Worked a RU
station on 80 from KL7 so they do emit a signal. It was a good aerial, easy to
build, with some vertical component to the pattern.

Well, you'd have a slant or tilt polarized radiator. You could make the
top horizontal wire a 1/4 wavelength and let it be an elevated radial and
treat the vertical wire (probably bent horizontal at some lower altitude) as
a vertical radiator, but you'd still have a tilt polarized radiator
That's a good one for 80m from KL7! FB!

The only real way to tell is have one of each, and do many instant A-B
comparisons over a period of time.
I just have two 10'+ high elevated radials on my bottom-fed L. It seems to
work well, but I should add more radials this summer. And that's what
I'll probably do before I ever build one of
Well, I've worked a lot of good stuff all over the world on 160 with an
inverted L with two elevated radials - because that's what I had room for.
If you get up to 4 symmetrical elevated radials there's not much to be
gained by adding more. There's been a lot of work done in the broadcast
industry
Found paper logs from July 1997…it was VP8CTR on 3796 SSB at our SR, and a
Ukranian base not RU. Still, Cebik's L worked.

The real key is symmetrical, according to the stuff I re-read earlier
today by Rudy, N6LF and K9YC.
Mine aren't symmetrical. The N radial is straight; but the S radial has to
zig-zag, because I'm too close the neighbor's pasture fence. The current is
almost certainly different on each radial.

Yeah, but this is 160, and if you can get the bend up 75 feet or so you are
feeding a half-size doublet that consists only of a

I have yet to hear about a ham who had 120 buried bare radials
underneath his two raised radials.
ON4UN's original 80 meter wire 4-square hug around his 160 meter
tower came close to that description. The 4 square had a single
elevated radial for each 80 meter element but they were all over
Thanks, Guy.
If I ever try this, it will very likely be on 80m first, and each half will
be 1/4 wave.

Oh, OK. That should have worked. And note who you're talking about. :)
But have you heard of a ham that had 120 1/4 wave bare buried around his
130' insulated tower, and then switched to two raised radials with the 120
left in place.
Commercial BC is in the fix of having to maintain the field
That's certainly true!
