How much weight can a push up mast carry
 

Hello All,
I've justed moved into a new home and the XYL isn't crazy about my
plans to build my "dream tower" just yet. I was wondering how much
weight a push up telescopic mast such as the Rohn 50 foot guyed unit
could safely carry. Specifically I want to mount my MFJ 80-2 meter
vertical, which weighs in at 20 pounds, and an 80 meter dipole on a
side arm mount. Any thoughts from the group that meight prove helpfull
are welcome.
Thanks and 73,

If it's well guyed and you keep it vertically straight it shold be OK
as far as the vertical is concerned. I'd be leery of hanging the 80M
dipole on a side arm because it would generate a torque load on the
mast which could cause problems. I'd forget the side arm and hang the
dipole on the mast as close as possible to a guy level. There might be
some issues with interactions between the vertical and the dipole on
80M.

Thanks for the advise Brian. I'll keep that in mind when I get around
to setting my new shack up.

Hi Rob,

Gotta' ask 'ya. Didn't you tell your bride-to-be that you were a ham, and might
need an antenna, before you asked her to marry you? Something like a pre-nup?

I've told all of my wives that I was a ham and they better get used to
it. My current (and permanent) wife and I spent two years shopping
for houses on acreage without deed restrictions before we bought here.
She was fine with that. Put up a 60' motorized free-standing crank-up
tower, trash that MFJ and put up a Christmas tree and enjoy yourself.
If this is an issue, find another wife :-)

Hooray for Linda, Wes, she's got her head on straight. My first wife, Harriette
was one of George Sterling's assistants as Chief Eng of the FCC before I met her
in 1940 at the FCC Allegan Primary Monitoring Station, where she worked after
transferring from the Washington office. So she knew hams long before she and I
met. I had been a ham for seven years before we met, so she knew what she was
getting into and she encouraged me in every ham activity I wanted to get into.

Unknowing to us monitoring guys, she knew the code. We all had code oscillators
at our work station, and we often made remarks across the room about her via cw.
Little did we know that she copied all our remarks, and had some pretty sharp
comebacks for us. It's not only due to my being a ham that all four of my kids
are licensed, as well as my son-in-law. Harriette had a lot to do with it. My
oldest son Bill, W2WM, is already retired, and has been licensed for 38 years.
Son Rick, WB4GNR, a computer engineer with Agilent, has also been licensed 38
years. Daughter Sue and her husband have been licensed for 25, but son John,
K4JRM, has only been licensed for a little over a year.

I lost Harriette to emphysema in 1985, but in 1996 I found my first love, my
high school sweetheart, after neither of us knew where each other was for 61
years. We married on the island of Anguilla in 1997, living in my home in
DeLand, FL in winter and in her home in Mt. Pleasant MI in summer. Jean is an
emeritus professor of speech at Central Michigan U, and also supports my hamming
emphatically. She did all the proof reading of Reflections 2 prior to
publication. Enough gab for now,

Before I married my wife (40 years ago in August!) I showed her the
ham shack and had a QSO on 160m (AM phone in those days!) with her
present. I let her say hello to some guy across town, warning her that
it was illegal in the UK then for someone unlicensed to speak over
amateur radio so she'd better make it quick. Her first words on 160m
were, " I think I'm breaking the law by talking to you...." !!! Thank
God it wasn't 20 metres or the whole world would have heard her!

She's been very tolerant ever since...

Peter, G3PHO

Guys! Really! Seriously, she knows I'm a ham. We've been married for
almost eleven years, and this is our first brand new home. We designed
the home from pencil and paper up, everything IN it together. But what
goes OUTSIDE in HER landscaped yard is something else. I've gotten the
Queens permission to put up a tower on the back ten acres once the
trees between hit tweenty feet high. until then I can live with the
push up mast. Heck, now I'll have a new piece of gear for field day in
the future. HA Ha.
Thanks for you concern for this poor put upon soul in the arm pit of
Ohio,

I think the proper forms are available for download (as PDFs)
on the ARRL website. :-)
