The same though came to me too Booty.

I will try to get the Eznec settings for my A/P to specs, as close to those for the Merlin first.

I have a recollection about the A/P however. I seem to recall it is very sensitive to changes in height. I did a thread on this in the past, and use the A/P to demonstrate the idea. I think I even asked Homer if he had ever experienced this with his A/P. So, I'll have to refresh my memory on how that all worked out and why, just in case it crops up and I'm asked. Homer, do you remember us ever talking specifically about this idea of height and the A/P?

On the other hand the Merlin model shows very little effect on match when I raised or lowered it between 18' and 54'. The A/P may not work the same regarding changes in height, but I will check that for sure.

However, right off the bat I would guess the A/P to be a bit better in gain and maybe angle. Booty, IMO this would be due to the A/P having a shorter radiator, by about 1/2, allowing the feed point to be installed higher...if we are comparing with the antenna tips at the same height. The difference in radiator height between these two is the A/P is about 47" and the Merlin is about 75" inches.
