[VHFcontesting] Yagiphobia, Confusion and Infusion

[beamar]

If you do the arithmetic, that is about right. M2 claims 20.5 dbi for the 13WL. I will bet that the loop down around 1 dbi. The yagi is at 100 feet and the loop is at 75 feet. The loop is side mounted and the yagi is out the top. The loop is on 5/8 inch heliax and the yagi is on 1 1/4. So, I would say that the performance is about what I would expect.

I'd say you have something wrong with your 432 loop if it is no better 
than the back-end of your 13wl M2 yagi, which has a f/b of 22db.

As to the performance of the 432 loop, the gain should be just the same 
as any other loop for any band. Again, if yours exhibits poorer behavior 
there must be a problem. All loop designs are, essentially, dipoles 
wrapped so the ends almost touch and they can be circular, square or 
triangular...anything works. No loop design is going to be substantially 
poorer than any other loop unless there is a design or assembly issue.

Regarding your 6-meter yagi pointed north...when we were in HC we worked 
21 FL stations on 3/18 and 4/14/2013, including a couple of stations in 
EL98. We also heard at least one beacon from FL, which was audible for 
hours with no one responding to our CQs on CW and SSB. You are in a 
sweet spot for working single and multi-hop sporadic E to the Caribbean 
and, to a lesser extent, South America even with poor solar activity so 
having *something* pointed south would be a *real* good idea. This is a 
place where a loop can be of value.
