We drill a tiny hole so water doesn’t build up in the leg. So I am clear though, you are saying the legs split when they fill up with water AND then freeze?

I've seen a few tube towers - including a very nice one - bursting apart due to the customers putting the base right into concrete and not leaving a way for the water to drip out the bottom.

Tushar, We buy Rohn 25G, with a landed cost of about $ 130 per section. Figure $ 80 in concrete (probably a little high) and we stick 3 ft. of the first section in the ground. We do the first piece (dig hole, pour cement) in about 2 hours times 2 people (on average) then come back in a day after cement hardens and we stack the other pieces (sometimes 20 ft. at a time, sometimes 30 feet at a time, but figure another 3 hours on site times 2 guys. That includes bracketing to the house. However, that part is a big variable though because of home construction. You shouldn’t just attach to an eve without beefing the eve up. Rohn also makes various size stand offs that can go to the side of the house. So, about 10 hours of labor on averages, and probably $ 650 to $ 750 in materials for a tower of 37 feet. If your highest attachment point is high enough and solid, you can stack another 10 foot section There are some variables in there, but that should give you a decent estimate.

I don’t understand why customers don’t blink an eye signing 2 year contracts on cellphones and satellite service, but resist investing in a Rohn tower which is an asset with about a 30 year life and also gives them a place to mount things like an OTA TV antenna, security cameras, etc. Not sure if they think it’s ugly, or just don’t make financial decisions for the long term.

I don’t know comparatively Tushar. We have found that 50mph winds for an afternoon is all it takes to bend them. Being on the ocean, we also see them corrode rather quickly. 2 different brands of poles and within 2 years they are almost unusual, parts break trying to loosen them to lower them etc. They just don’t last and then whose responsibility is it to replace them. The customer doesn’t want to pay twice that’s for sure. The other problem is fine tuning… east/west is OK, but up/down angle of a dish is a PIA. 320 CPEs are not as bad on a pole for tuning, but the other issues really hurt us. We would rather try talking the customer into a Rohn 25 40 feet or a bit more depending on highest building attachment point so that we are not guyed. Even if we do that at parts / labor cost, its much better long term, and easy to service the radio.

Your point on sector efficiency is the reason we no longer like NLOS installs. Yes you may gain few customer with little less effort but in long run it hurts. We try to install 40 to 50 feet push-up poles and get better line of sight.

For me, it's too expensive. Every way I run the numbers, I'm looking at 16-18 months for break-even. And that's not including all of the extra stuff required for a large scale deployment. If I can't get 25-30 users per sector, the site is too small to deploy it. If I'm running a bunch of NLOS customers (which we would since we're about 55% 900MHz), lots of low modulation users really sucks for sector capacity. And those NLOS shots, like Ken says, will they continue to work? When the trees are soaked, covered in ice, etc., does it go to shit and I have to listen to customers bitching because they were getting 20+Mbps and now get <5Mbps? Which again is a hit on sector efficiency.

We should have been suspicious when aligning for best signal actually had the CPE pointed up at about a 30 degree angle. I have seen something similar with 900 MHz.
