I have just built a 80 mtr dipole c/w 1:1 balun ,feed with RG8X coax
works great, really dont even need a tuner(which i am trying to get away
from)
here is what i want to do.I would like to get 40mtrs on it,without using
tuner,so I want to use a couple of latching realys to open the dipole up
at the 40 mtr section of the dipole,1 relay for each leg.
I want to use latching relays so they do not have to be energized when i
am on 80mtr portion or viseversa if i use the normally closed contact.I
was going to feed 1 end of the realy coil from the sheild of the coax and
run 1 wire for the other side of the coil to my switch point.Does anyone
have a better idea on how to do this or is this all a waste of time.If
this is ok to do and worth it does anyone have a realy PRT# I could use,I
only run 100 watts max
Also i have tried to strap on a 40mtr dipole to the 80mtr and the 40 would
not tune at all and I dont have the room to run the 40mtr dipole away from
the 80mtr
thanx

I found this very interesting:

and has the advantage that the switching is not in the antenna elements.
