[TowerTalk] 40 metres yagi - Your advice matters

I have the JK 2 element coil loaded JK yagi with 47 ft elements.  Very impressive mechanical construction.  The Grande is built massively.  There are pictures on jkantennas.com and on the facebook page.  I know there are Grande models all over the world, some even stacked.  I have not heard of any problems at all with them.  I've talked to hams in Fla., Kuwait, Japan and WV, all using the JKs successfully.
