Short dipole - inductor question
I plan on building a short dipole (inverted V) for traveling in my tiny
RV. It will only be designed for 75M. The mast is 20' tall, and I wish
the legs to be about 24 feet each.
I still haven't decided where to place the inductors, but in any case, I
have a question about their design. This antenna will only be used at the
5 watt level with a FT-817 Yaesu; an LDG Z-11 tuner is also available, but
probably not needed.
If I make my 75M dipole legs for about 24 feet long, then I figure I
will need about 70 uH inductors if they are center located.
My Question: What would be the requirement for a 70 uH inductor that
only needs to work with 5 watts? Do I need open air inductor with spacing
between windings, or would a smaller multi wound coil with insulated wire
suffice?
Thanks for any opinions on this.
