Doug and Phil,
I checked with the crew to see if we had any old parts laying around
for that antenna and we don't.
The reason we stopped making the drooping radial vertical whip
antenna is that the radials had to be 1/4 wavelength as well as the
vertical whip. The bandwidth was a little more than a block so we
would have to have had to stocked lots of machined parts. In contrast,
the SNA 600 dipole has a wider bandwidth, same basic performance and
can be adjusted for frequency. Since it is frequency adjustable, we
and our dealers and our customers only have to stock one version.
That's also the reason we do the log periodics. We only have to stock
one "all block" antenna. That leaves us with the whip antennas. These
can be adjusted to the correct block with just a set of cutters. We
can make up lots of them with extra length and then trim them to
frequency shortly before shipping. This is also why we don't build
Yagi antennas. They have to be built to frequency.
There is a definite downside to building our units from block 21 to
block 33. This is a major reason why we are frequently (very
frequently actually) out of stock on a given model in a given block.
The number of possibilities of models and blocks is bog mindeling.
Having to make relatively complicated antennas special for each block
just adds to the shipping problem.
Best Regards,
Larry F
