when an LPDA will do the same thing with no moving parts and, at most, 2dB
of claimed gain.²
Of course, there are still trade-offs with a LPDA. N4CC and I recently
purchased a Tennadyne T14 (30m-10m) on a 42 ft boom. The primary reason
for the LPDA versus mono-banders - or other multi-banders, is that it is
being installed on a tapered, 100 ft. self-supporting tower that's going
up in a couple weeks (tower prep photos on my QRZ.com page).
If we had a sectional guyed tower, the choice would probably be the same.
We would rather maintain one reasonably good directional antenna in an
intense lightning environment than a full set of mono-banders where a big,
fat vertical profile isn¹t needed - unlike the case of contest station.
The two self-supporting towers are not new (the other is 140 ft. for 40m),
and to us, it¹s not worth abandoning them in favor of guyed/rotating
towers.
