Atlas install pics
« on: April 08, 2019, 08:48:26 PM »
Weather is finally warm enough in MN that I could drive a post in the ground.  Setup the Atlas in its final resting place.  Pretty much out in the open about 125 ft away from anything taller than the anemometer.  Excellent signal strength at the receiver in the house with direct line of sight through the window.

Mounted on a 10 ft EMT pipe and then zip-tied to a u-post.  Pretty stable but does have a little flex but no worries about falling down in a strong wind.

Thanks for posting the pictures. I always enjoy seeing other peoples installations. If it were me I would consider backing up the zip ties with some stainless steel hose clamps.

I agree the sun and UV will weaken them zip ties and they can break.

I have had weather stations installed for over 20 years. About 8 with Davis and the balance with a Dallas Semiconductor station. (no longer available, but used TxWx mechanicals).

My experience has been the the "natural" nylon tie-wraps are indeed susceptible to drying up and cracking in UV after a few years. They get quite brittle and I have had them fall apart on me.

On the other hand, the black "UV resistant" ones have never given me any problems and have been up for years without a problem.

Where I live in Michigan isn't a high UV location and I know that in the high desert in the SouthWest, the UV is brutal.

The only caution I would have about clamps is the possibility of the fairly sharp edges cutting into the cable, especially if the wind catches it and begins moving the cable against the worm clamp steel edges. I think that I have seen some rubber covered clamps, but this might get you right back into the UV issue.

I would wrap the cable with good electrical tape in the areas that will have the clamp to protect against this possibility.

My suggestion was to use hose clamps to attach the 10' EMT mast to the "U" post. I don't see any cables near there. I would never use hose clamps to attach cabling.

I do agree that the UV resistant black ones (as in the picture) are much better than the normal white ones.

Thanks for clarifying that, I see what you are talking about now. The worm clamps would be much better for attaching the mast to the post.

I use stainless steel ties that I get at Ace Hardware. Work just like zip ties.
