Topband: 160 meter 1/4 vertical

Forget about the high impedance issues on 40 and also 80.  IMHO the best
and easiest solution for you is to make some simple wire decoupling sleeves
or wire cage for the higher bands and they could be current fed like 160
meters and much less complicated to feed without extensive matching.  Also
1/.2 wave vertical are notorious for not working well with some obnoxious
lobes.  The only full wave verticals that I know to work are of the
Franklyn antenna design and require a decoupling at the 1/2 part with the
other 1/2 wave above it.  This is said to produce some low angle gain and
essentially double the radiated signal without the wasteful lobes at much
higher angles.
