[Elecraft] Antenna choices

[kd7gc]

Joshua, Multi-band yagis operate on the bands that they are designed to work
on.  If they worked on other bands, then all of the bands that it worked on
would be listed just as all of the others.  A tuner may be able to tune an
antenna up on a band other than what it was designed for, but it would
likely generate terrible SWR, and would therefore be very inefficient.
Determine what bands you want you yagi to cover, and buy one that matches
your needs.  The cost of a rotor depends in large part on the size of the
yagi that it will be turning.  A yagi with a 14 foot boom could be turned by
a very small rotor, but a yagi with a 50 foot boom will require a very
large, and very expensive rotor.

Ok, I know that this is a topic much like the Ford vs. Chevy debates or the 
Android vs. Apple debates, but I do have a few questions... 

I am going to be acquiring a 56 foot Rohn BX tower.  I already have a G5RV 
that I am planning on putting up (still not sure where I'm going to attach 
the other end of it to, One end will go on the tower.) I'm going to put up 
a 2m/440 vertical at some point up near the top of the tower.  I keep 
throwing around an HF vertical or a beam.  The verticals seem to cover more 
bands, but the beams are directional.  (Would also need a rotor,.. 

Can a multi band yagi be tuned to a different band, or will it only work on 
the bands that it's designed for? 

I'm thinking long term and I'll probably be adding a K3/100 with a KPA500 
to the mix in the next year or so...  Trying to figure out what will give 
me the best bang for my buck, so to speak.
