[TowerTalk] DX eng

I don´t think it is a good idea to use saddles with teeth.
Those will saw through the tubing on the long run.

I use single mounting plates on all of my antennas.
Mating plates are welded to the rotating mast.
All mounting holes are the same on all plates, so any antenna will fit at
any position.
And I use commersial DIN mounting material (stainless steeel only) on my
antennas like those by Stauff:

I only use stainless steel hardware in my antennas and after recently 
dismantling my P40A station I was glad that I did as even in a corrosive 
environment, everything easily came apart.   OptiBeam comes with all 
stainless steel hardware and they use a laser cut SS saddle with teeth which

seems to be effective.  What is wrong with their single mounting plate?

##  and nobody
##  Just about every U-bolt on all my F-12 yagi's  is rusted.. sometimes the

u
bolt threads... and
sometimes just the nuts.. and sometimes one/both halves.   You got any idea
what is involved
in taking rusted hardware apart?    Every thing from power hack saws to zip
wheels, to air/electric
impact guns, breaker bars, torque wrench's, wd-40, etc.

##  after  38 yrs of ham radio.... that's  it for me.... if it's not SS, 
It's
not going up there.   I'm not talking abt
tower leg bolt's either... just ant hardware in general.   Evert tried 
getting
a yagi down... then find out you have a
bunch of rusted out U-bolts up there ??



##  sure dx eng is not cheap,  but their products are all on one site, and
service is 2nd to none.  If you want to see
expensive... check out opti-beam's  prices.  Opti beam still hasn't figured 
out
how to make a real  boom to mast
plate set up.  Single plates went out the window almost 20 yrs ago.

later... Jim   VE7RF
