I have a coil version being built right now to upgrade a new 40m4lldd that has
not been installed yet. We have high winds where I live and mike and team has
done a great job in this design. Bandwidth is the same as the linear loading
and he extends the boom by 4 feet I think. Contact Jason at m2 for a quote.
The option is not on their web, but they will offer the upgrade if asked. I
also have them building a 80m2 for me that is going on the hdx-689 that I just
finished installing. Mike did comment that the 4 ele 20 add on for the coil
version was not ready yet.
Thanks, Rich. N7TR
