log periodic antenna...........what have you got?

Bob,

If your willing to experiment a little,
Antenna Compendium 3 has estimates for a log periodic loop array.

I have never heard of one being built. W1NMZ said that he had modelled
one and it performed similar to prediction with the exception that I had
overestimate the gain over a traditional log periodic dipole array.

One design detail that I have not figured out is the spacing of the feed
between adjacent loops.

With respect to dimension, if I recall correctly, the overall length was
about 36 feet and the widest element, the reflector, was about 24 feet.
This would result in a turning radius of about 30 feet.

If you decide to try out the LPLA, let me know. I am very curious to
see if the design works. I would be glad to assist you.

Good luck,

Look at the 6 element Tennadyne T6. http://www.tennadyne.com/
Very well made and works just like the specs. say it should.

I would also chime in as a very satisfied current owner/user of the
Tennadyne T-6 Log Periodic and formerly a T-10 at the old qth. Very well
built and does what an antenna of it's size should. At the prior qth the
T-10 (24' boom) went through FIVE major ice storms without obvious damage
(although when I took it down to move I did notice a crack in the boom at
the rear of the antenna (largest element)). Tennadyne has since re-designed
the booms, and the T-6 now uses two rectangular booms. If you're not a
big-gun dx'er and just want an antenna that does a very good job from 20-10m
with moderate gain and excellent f/b, then the T-6 would be a wise choice.
It's also quite reasonably priced, has low wind loading and weight.

I know it doesn't really mean anything but I started working on DXCC when I
put the T6 up 2 years ago. I now have 273 countries worked and have DXCC on
20/15/10 and I'm waiting for cards for 17m, all on phone. My antenna is at
40' due to local height restrictions. I couldn't be happier, well not true,
the SWR on all bands meets specifications but is higher than I would like,
A maximum of 1:1 would be nice but it's not realistic. The T8 specifications
are for a bit lower maximum SWR. I keep thinking it would have been better
to have. But with size, cost and my location considered, the T6 does the job
very well.
