I called up to order several more of the DX Engineering dipole baluns
yesterday to build some Field Day antennas. I was told that they are
discontinued, and that as a "replacement," I can order a balun in an
aluminum enclosure. The reason given for discontinuing the balun was
that its construction made it difficult to manufacture consistently.
While I can accept that the relatively compact size of the
discontinued balun might have been a limitation, I can't accept as
fact that some other form of balun more satisfactory for use with a
wire dipole than one in an aluminum can couldn't be built -- perhaps
one in a longer tube that allows the coax to come straight away from
the antenna for distance long enough to support the ferrite cores. Is
there something else I'm missing? Am I limited to buying a bunch of
cores and putting them on coax myself?
And I still have to come up with a decent center insulator/support,
which the discontinued part did QUITE well, and which the proposed
replacement doesn't appear to do at all. Has no one at DX Engineering
ever built or used a wire dipole, other than perhaps as an inverted
vee supported from a tower?
