Hello,
Remember when Phelps
Dodge/Celwave/RFS came out with a competing 4 pole exposed dipole? I was
working for a nationwide paging company and my boss had Motorola Batwings
tattooed to the backside of his eyelids, of course that meant he only
used Phelps Dodge antennas, I think the number was PD-341 TP (TP stood
for Two Piece).
Long story
longer. At every site where we installed them they showed a lot
more reflected power on a Bird 43 wattmeter than the DB-224 or
DB-301. Usually from 5 to 7 watts reflected with 250 watts
output. This was way before the sitemaster.
I always liked the DB antenna
better and that certainly proved it to me. I have had a DB-410 on a
building top in Fort Worth for over 25 years and it was a used antenna when I
got it! By the way, I personally know two of the engineers that designed
that antenna for DB, great guys.
By the way, my boss had to eat
a lot of crow when all of the Technicians coast to coast reported the same
thing, yes we went back to DB and had no further problems. I still have a
PD-340, well the mast at least. I am making a lightning arrestor for my
tall tower out of the single piece aluminum mast!
