Let me guess, John - the rotary dipole used a BN-86
balun right? They are notorious for being fuses. A coil
of RG213 on a piece of plastic drain pipe will work just
fine (especially for a monoband antenna):
They recommend 12 turns on a 4" form. I would go
with 8 turns on a 6" form.
If you want something a bit smaller, you can also buy
current balun's from DX Engineering or Array Solutions
which use ferrite cores.
