<Hopefully - the 40M yagi has the elements connected to the boom.

Just came up with a method to bond the 40m REF + DIR to the boom.

 By adding one vac relay to each nema box, I could just electrically

 bond the flat strap coil inside each nema box...to the boom.

 Activate both relays when on 160m.  I have a mess of new DPST-NO
Kilovac relays.

 I will parallel the contacts on each relay.  Problem solved. Then the 40m yagi

will appear as semi decent top loading...esp with the 50+ foot long eles.
