Rather than using banana plugs or alligator clips I suggest to cut the
dipole to SSB and add a linear piece of linear loading at the feedpoint to
both sides to retune the dipole to CW. If you want to operate on SSB you
simply short the linear loading with a relay, which cancels the loading
effect. I used this method on an Inv-Vee I still have. I needed 1.2m (4 ft)
long loading element with 10+10cm (4") spacing (3530 for CW, and 3760 for
SSB). The relays I used were common 400V/10A SPDT's fed via the coax, which
would also suit you for 1500W.
With this solution you get the luxury of not having to run out and climb
towers in a multi-mode contests. :)
