Got a question for crank-up owners: Do you crank up your towers only when you are operating, i.e. 95% of the time they are nested and only go up when you turn on the rig and start looking for a qso,
Rob: Living on a city lot with a 2 el 80-40m Yagi on the tower makes it best to keep my tower DOWN except when QRV. The neighbors sure appreciate it, and for that matter so do I...to a Ham the Yagi m

<snip> The short answer? When I come in to operate I expect to turn on the switch and go. When I finish operating in the evening I point the antenna where "I think" the band will be open when I get b
Roger... Well ok, I guess that makes some sense. However...I can wait the 4 minutes till its at full height (100'). Truth is, in 2 minutes the tower is at 50 feet and is still "good-to-go" If I'm at
When your 70+ years old "how many times are you going to crank it up or down"?? Or is it just easier to "FLIP" the switch like I do. On the qestion of height or extension, I only raise it 90% and tha
Rob: Generally, the 72' tower at this QTH is parked just shy of 100%, unless bad WX threatens or we are leaving town.Then it is motored down to around 50% or all the way (about 22' fully tested). Ove
Interesting, never considered speed. This thread is kind of mixing "crank ups" and "motorized", but the feet-per-minute issue still is a factor I've owned hand-crank and motoroized. Don't want to sta

Sounds like an airplane. You either spend a lot of money flying it, or a lot of money fixing it if you let it set. Roger Halstead (K8RI and ARRL 40 year Life Member) N833R - World's oldest Debonair C

The only times mine comes down is when there's antenna work to be done, or there's plenty of advance warning of major storm conditions. It lived through the 1987 and 1991 storms when the wind speeds
I've had more crank-ups destroyed than most. Some were operating error and some were Mother Nature smacking me around some. K7LXC has some pix of what happened to a crank-up when a thunder storm cell
My Tx-472 (notice it doesnt say TX-472MDP) stays at full height most of the time. when we are supposed to get big weather or i am going to be out of time for an extended time i will crank it all the
Not mentioned has been the notion of not leaving a crankup in any one position for longer times. This is supposed to be somewhat harmful to the rope. Without thinking it would be easy to leave it all

Rob on the tx-472 and probably most or all US Towers the cable is the only thing standing between a nice looking tower/antenna system and a pile of scrap metal... ____________________________________
There is little doubt that crank up towers in the 70-90 foot class require some special maintenance considerations. They are pushing the mechanical design envelope by their shear weight and potential
The same can be said for my guyed tower. Rob on the tx-472 and probably most or all US Towers the cable is the only thing standing between a nice looking tower/antenna system and a pile of scrap meta
