You have it correct.  It's just a 43 ft aluminum pole.  Run that thru 
EZNEC and you can see what happens to the radiated pattern on the high 
bands, and notice the impedance on different bands.  Yes the SWR is 
high, which is the reason long feedlines can have a lot of loss 
especially on 160 where the real part of the impedance is very low.
