i have tried both the dx engineering reversible and the kd9sv (available at
dx engineering). both work well performance wise. i think the kd9sv is
easier to string up because you use a much smaller telephone wire, whereas
the dx engineering uses ladder line. the plus with the dx engineering is
you only need one feed line back to the shack. the kd9sv requires two.
however this can be a plus if you want to phase the reversible and create a
misek type beverage. in terms of phasers, I have used the quantum phasor
and the ncc-1. the quantum works better for mw. however, the new ncc-2 has
filter slots and filters to optimize it for mw. i have not tried this
version but I'm sure it works great.
