Hi Bill.I have a JK 30/40 and I can attest to the robust construction of this
antenna. Also, my swr from 7.0 to 7.2 is under 2 to 1. The JK 30/40 is mounted
8 feet above an XR-5 yagi and they work well together :)73,Paul W2JGQ In a

In the process of what to do about 40 meters at my new location and I have a
few questions for the group. I will have one 126 or 136 foot tower (Rohn 55
with Phillystran guys. Plans are to stack two 2 2-element Yagis. I've
narrowed it down to the Cushcraft XM-240 and the JK mid-tri 40. Realize they
are two different approaches to the issue but I have lots of different ways to
go. What I am concerned about ...First, I have spoken to Ken at JK and he
assures me we can get less than 2:1 SWR from 7.0 to 7.2. The Cushcraft's info
says 250kHz for the XM240. I'm curious as to other's experiences with either
antenna as far as structural integrity, band width, performance, any issues
etc. Also wondering if anyone has stacked these and what effect it had on the
SWR curve.Thanks for the help.Bill
