This turned out to be a very nice mast.
The bottom portion slips snug over a 1.625" ( 1 5/8) fencing tube, which made installation very easy. Hardest part was digging the hole for the installation post I used.
Installing the guy cables was a cinch using the guide supplied with the mast. Just remember to cut them to length and install to the mast before extending, then tie them onto your guy poles and tighten as you go up starting with the bottom section.
Mast is well made and certainly strong enough for the Starlink dish I put on it. Strong and light enough one person can install it alone (I did).
We have our first gusty-windy day today, and it is holding position perfectly with no internet drop out at all.
Highly recommended for the do it yourselfer, just takes a little planning before you get going. Cement in your guy poles, cement the base tube if you use one like I did, and away you go.

Great product. YouTube video was great !
