I am debating putting up three or four guy wires toward the top of a 30 foot tall mast that currently has a Maco V58 antenna on top.
The bottom two sections of the mast are 11 gauge "1-7/8" x 11' Galvanized WT-40 Chain-Link Fence Line Posts. There is a 16 gauge, 6 foot long sleeve inside these two pipes that overlaps the joint. It's a very tight fit so less than one mm of wiggle room. Grade 8 bolts secure the sleeve inside the outer pipes.
The next two sections are GENUINE ROHN 5' Steel Tubing - 16 Gauge Steel Mast Pipe with Locking Joints. About two feet of the mast overlaps the larger pipe section below. The masts are secured to the main mast by four stainless steel double U-bolts.
Then the Maco V58 sits atop the second mast.
The mast is secured to the house using two Easy Up 18" Stand Off Wall Antenna Mount for Masts 2" - 4" Y Style Bracket - EZ 30-18W. The brackets are attached to pressure treated 2x4s that are attached to studs behind the vinyl siding using hardware appropriate to the environment. The lower bracket attaches to the mast at a height of about 3 feet and the second one at a height of about 10 feet. That's as high as I could go.
The mast itself sits in an EZ32C Telescopic Antenna Mast Heavy Duty Base Plate and the base plate has a spike in it that is driven into the ground to both keep the base plate from moving but also to have the mast slide over it and be locked in place with a capture nut.
This setup leaves me about 20 feet of mast plus the V58 above the top Y support. It seems quite secure and heavy duty but who knows.
The problem I have is I don't know where to install the guy wire anchors. We just spent about $25K getting the roof replaced and don't want to hack into it. The entire house has a 16 inch overhang where the gutters mount so getting a guy wire from the ring on the mast down to an anchor on the roof fascia is troublesome. I can just wrap the guy wire around the gutters because it would destroy them I could come up with a mechanism that attaches to the bottom of the soffit then does a 90 degree turn up high enough to allow the guy wire to attach to it. Seems like that might possibly be a lot of torque being placed on that type of setup. Even if I did that, that would cover the mast to the NE and the SE. I'd need a third guy wire on the west side of the house which is the side of the house where the antenna is mounted. The best options I see there are some very large trunks for both maple and oak trees. If I did that I'd want to make sure it's not a safety hazard.
I do plan on putting up set of beams next spring. I may either use something like an M103C on horizontal with the V58 vertical or an M104C horizontal again with the V58 vertical. If I went with the M103C I would probably just stick with this mast as long as I can get a suitable guy wire arrangement figured out. For the M104C I'd go the tower route but I still may have to guy the tower unless I fork out for a freestanding one.
Any of you folks ever have to run guys wires on a roof with a 16 inch overhang and gutters? The roof is multi-faceted so no really straightforward anchor points that I can see.
