let me suggest a plan B -- if you would like to operate on more than one band consider an 'End Fed Half Wave.' many homebrew references on the web. also check out QRPGuys here in the US - they have some nice inexpensive EFHW kits.
'counterpoise' is merely a poor approximation for having many radials. advantage of the EFHW is that the 'counterpoise' shrinks to being very small, because of the unique physics.
if you expect to have some space, I strongly recommend the EFHW. if you are on a ridge etc with no trees - QRPGuys has a cool matching network to use with a 'Squid pole' vertical.
ham radio is about learning - keep at it ! enjoy your radiations with that new rig !

PS - there is a trick to use an EFHW over 80 to 10 meters, by placing a little coil near the feedpoint. this is described various places on the web.
