[TowerTalk] Upgrade

[Timothy Coker]

I’d echo Mike’s statements. I have both the Mid Tri and the Mid Tri w/40m on my tower along with the 801T at the top of my mast.
The 402T is a design I’m considering for my next tower project if I don’t go with a 4 el OWA, so I understand the interest for sure.
The 2 elements on the Mid Tri have a great build to them. I’m feeling louder on 40m versus my XM240 and it’s really just a bit more due to the efficiency going on with Ken’s coils. SWR curves aren’t as nice but that’s because it’s less lossy. I’m 2:1 at the amp output from the bottom up through 7.205 with my run of coax.
With the savings on my mast up top by bringing the 40m onto the Mid Tri boom at 1’ above the thrust bearing I was able to add the 801T and wow did that ever make 80m feel like something new at my QTH versus an inverted v!
JK’s build quality is quite robust. No experience with OptiBeam and I was looking hard at them too.

If you're already looking at the Mid-Tri, consider the Mid-Tri-40. Separate
feedline for 40 and saves you some windload and mast space. See:
