< Hi Jim,
<Sorry to sound dumb, but what is an hb coil?
<73, Rich, N6KT
## HB...AKA ....home brew !
## I used 4.5 inch OD PVC for the form. Once coil is wound, turns
tight, its slid off the pvc form.
Turns are then spaced out to spec..starting with a screw driver at one
end...spiraling round and round .
Repeat for the remaining coils.
## I used .375 od tubing for the hb coils on my F12-340N. Ends
flattened, then punched for the .25-20 hardware.
In my case, aprx 5.5 turns.
