Not in my opinion. Having the mast in the center gives it the same
stability from all win directions. If a big wind is coming from "behind"
this might be more "tippy". Besides, you only need to use one mast.
You can also build almost anything you want out of unistrut.

Would this be a better solution than a single vertical so I have
something to affix the strut to?

Our wall mounting option for the 4' antenna is limited to the 25g
we ran up the side, the antenna will actually be 75 feet up the
wall from the first platform I dont think unless we installed a
standing platform we would be able to adjust the antenna.
I think Im calculating right, its going to take 500lbs ballast if
I used a PRM4, but the lead time on those exceeds our timeline so
Im looking at the sitepro tripods.
We are kind of limited to the non penetrating solution because
with that we dont have to have a mother may I in place
A penetrating mount we will, and if a board member says structural
analysis we are shut down on time.
So we are limited to horizontal surface mounts
We can get away with small concrete anchors, but we are talking
3/8" x 3" and I just dont see that that would be safe. Where would
I look to find the penetrating mount anchoring requirements, I see
ballast charts all over, but no anchoring specs.
On another note, Ive never dealt with 4' antennas before,
apparently this has a strut. How do I attach a strut if I only
have the single vertical mast?

At the risk of getting my testicals chopped off, I’d recommend
wall mounting if you can. SBWM-412 from Sitepro is $150 and
the HWK58 for mounting is ~$30. Throw in 6’ 0f 4-1/2” pipe
for $160 and your looking at a solid mount for $340 that takes
less time to install then it would take to lug the concrete up
to secure a non-pen with a 4-1/2” pipe on it. If you need to
use a non-pen, Id use:

That has got to be one of the best e-mails I have read in a
long time :-)
Commscope makes a nice option for a large non-pen mast – but
I’d steer away from anything with less than a 4” OD mast for
a 4ft antenna. Rohn makes a similar one, and Baird has a few
options.

*Subject:*[AFMUG] first approved licensed link mounting
I have two goals, mounting the bastard and grounding the bastard
If you knew the volume of fecal matter I have had to ea tot
get this achieved you would understand my very short fuse
about dealing with dickheads like me that I have.
I need to first mount this thing. Its likely to be a SAF
link, and thats that.
Im going to take a moment to say that regardless of what this
final project ends up being, if you want one hell of a sales
guy to work with, Jerrod from Moonblink(Jarrod Washington
[jarrod.washing...@moonblink.com
<mailto:jarrod.washing...@moonblink.com>]) is the shit, if
you badmouth him, I will come to your house, I will castrate
you, I will fry your man parts in olive oil, give them a
slight garlic and rosemary seasoning and serve them to you
over some white rice with a cane vinegar brandy. I float out
told this guy that after he did all the work, my bosses would
likely flat out price shop his parts list. He didnt blink and
kept on doing his thing. If my daughter was old enough, Id
marry her to him.
In a perfect world, both sites will be non penetrating
mounts. One side is 3' the other 4'. The side that wiull have
the 4' hast the option of being mounted on a set of 25g we
have running up the wall. The problem is the wall mount is
currently only secured every 20' with a 2" deep concrete
anchor, Im pretty sure this wont be sufficient for a 4'
antenna (currently we only mount 2' parabolics to it)
We have the option to plow through the wall with plates, but
if we go to that expenses we might as well go to a full non
pen for a 4" antenna at the top.
Any advice on a non pen mount that can support a 4"
parabolic? This side we can do pretty much whatever, but
still want the smallest footprint.
The other side, for non pen, our partner claims to have an 8'
x 8' footprint mount, the best I ever specced was 10x10 so Im
suspiscious.
Both sites are grain elevators. Im looking for the minimum
grounding to achieve a respectable level of protection. If
you send me an NEC link, you have no value to me, Im not
asking because I already know the NEC spec and just want to
brag about my testicles. I just want a rough Idea of what it
would take to get to a point where with factory spec
installation of a Lumina I can meet the minimum ground/bond
at an elevator and grow from there.
