I thought I would summarize what I have found so far. I have not made a
decision as of yet.
1. M2 - Makes a 3 element full sized yagi on a 4" boom with 3" center
elements. Rated for 125MPH survival. Weighs 350lbs or so. Cost $2500
They have also offered to custom build a yagi on a 3" boom with survival
to 100MPH for the same price. It's more work for them to custom make an
antenna, thus the price.
2. F12 - Doesn't offer a full sized 40M yagi but I have been talking
with Tom about a custom job using the parts of the elements he uses for
the EF80 80M rotary dipole. Price not determined yet.
3. DX Engineering - Bill is out of the antenna business but is still
doing switches and phasing boxes. He did say that he would build a 40M
yagi since it did not require the insulators that he used on all his
other yagis (that became expensive). Cost: $2500 He is not doing it
full time any more and said that I would have to be patient with delivery.
4. Texas Towers - Sells the aluminum and Gerald offered to help me with
the design of the elements and the boom.
It's amazing to me that nobody sells a full sized 3 element 40M yagi that
isn't a custom job, oversized job, or part time job. I know it's a
limited market, but there are more people making 2 element 80M solutions
than they are 3el full sized 40M solutions.
I think each of these sources have their positives and negatives. I
can't say which is best. I would say this is an individual decision and
I would suggest doing your own research on the subject.
