      I've installed several of them and they are quite an antenna. You get a
lot of performance for one boom and 105 pounds.

     The 20 works quite well and 100 feet is a 'sweet spot' for 20M operation.
One-hundred feet seems to work better than any other single height. 

     The only drawbacks on the 3L 40M are that it is fairly narrow in
bandwidth - it's either a phone or CW antenna but not both and that you have
to tune each element individually to optimize the performance. You have to be
able to reach the reflector and director to do it properly and it should be
30-40 feet off the ground. You can suspend it from your tramline and can rent
an electric lift for the weekend to do it properly. Any closer to the ground
isn't as good. 

     Go for it.
