Other solutions would be a self supporting tower such as AN wireless if
they still sell to hams or Trylon. At under 50 ft it is easier to deal
with especially if you could get a man lift near it.
I have a 70 ft self supporting tower which is great but after gaining a
pile of weight, which I am trying to shed and getting older, I sure wish
I had opted for something else that would be easier to maintain. I will
be 55 years old so I am a spring chicken in Ham radio but once I turned
50 my desire to do tower work declined dramatically. When I was younger
it seemed I was on them daily and never gave it another thought.
A crankup tilt over we be amazing, but they are very expensive these days.
