Need design info on coax traps for dipoles
Send me a valid email address and I'll send you a coax trap program written by

Good afternoon...
Anybody know where I can find some formulas or design information for
designing coax traps for a dipole?
I've seen some articles on coax-trap antennas but the traps they use are
too big. I need to make some traps for 40 meters that are narrower (but,
longer is OK) than the ones I've seen in the articles.
(A thought I had was perhaps using RG-174 instead of RG-58 ... these will
be used at low power only, 10 watts max)
High Q and narrow bandwidth is OK. These traps only have to resonate at
one specific frequency.
Any thoughts or advice?
Thanks...
