[CQ-Contest] Antenna Advice

[Don Steele]

To the group, I am new to this group.I am one of those "small pistols" in contests.I feel my station antenna system needs improvements,but I am real estate limited.Very small lot,not enough room for effective radials for a 40,80 or 160 vertical.I presently have an old Mosely TA-33 at 35 feet,Rohn 25G tower,Alliance HD-73 rotor.Also a Alpha Delta DX-B sloper,and a ladder line fed 135' Dipole,which takes up the entire length of the lot.I have the tower house bracketed at 15 feet,and have no problems with the present installation.I know they all need to be higher,but you have to live with what you can do sometimes.
   Any recomendations for a better tri-bander?I have been considering a Bencher SkyHawk or possibly a Force 12,but I do not want to overstress the existing tower,rotor setup,so I am limited.Also,any ideas for improving performance of the sloper?Would a short(40' max)set of radials at the tower base help?
   Thanks in advance for any input any of you could give.
