[Antennas] Trap Dipole Question

[Richard Solomon]

In making traps for a Trap Dipole, how does
one come up with the Coil size ? I can calculate
the inductance, but resonance can occur with a
great many LC combinations.

So is one ration better than another ? Does Q factor
into the calculation ?

Thanks for any guidance you can provide, I am
trying to come up with a design for a 60 & 30
Meter Dipole that I can use in an Inverted V
configuration.

Tnx es 73, Dick, W1KSZ
