Typ, the local power company will give u a few gallons? of xfmr oil.? ?I used that in the heath dl....and also my HB? 8 gallon DL.? ?But neither are used above 10m.?
?
Mineral oil will work too, but has to be de-rated vs the real deal xfmr oil.? (note the 2 x graphs on the heath cantenna).? ?Bird used some esoteric silicone oil in their loads.?
?
OP, how much PO are u gonna put into a DL on 435 mhz ???
