Thanks, Jeff. There are some mechanical issues with that in this
installation.
73, Jim ## another option is to cut the parasitic ele as a DIR. Then relay
switchin some uh in each leg...to make it a REF. You could run DCV up the coax
tooperate the DPST relay to pull this off. Easier said than done
though....espif the ant is used on both SSB and CW. 3-6uh per leg would
probably do the trick. ## another option, since you have a 120 ft tower....is
a 80m shortened rotary dipoleabove your steppir..and inline with the steppir
boom. No gain, but at least it has a 15 dbFS ratio....plus u can point it
anywhere u want. No increase in windload or rotor demands. Jim VE7RF
