Bill, I think there is some confusion as the question asked about calculating the effect of a mast was sent by k6xn and a copy follows. I responded to him suggesting that he could us the common value
John, Take a look at the Cubex dual band quad, SCORPION 88.or the smaller YJ-46 model. Web site is _www.cubex.com/uhf_vhf.htm_ (http://www.cubex.com/uhf_vhf.htm) Regards, Norm W4QN == In a message da
In reading through the exchanges below it appears that the term "Pipe" and "tubing" may be intermixed in the discussion. I am sure most know that 2" tubing (with a specified wall thickness) and 2" pi

Dennis, I can recommend a Dacron/Polyesther rope for antenna support work. The Black Dacron covering provides UV and abrasion protection and the Polyesther core is virtually stretch proof (unlike nyl
Bill, You can easily design a remote control system without the 5 sec delay devices. but you have to remember not to switch from up to down (visa versa) too quickly as motors with centrifical start s
I think you will find that many rotor plates just rest on cross pieces and webs. The TriEx LM-470 series of which I have had 3, all use this method. I have a spare rotor plate for the LM-470 if anyon

Having had 4 different crank up tilt over towers, TriEx and US Tower models, I found all required some persuasion to begin the "tilt over" process. Keep a crow bar handy for various alignment tasks a
General commentIn the past few years I have had the need to put together hundreds of 3" booms, and joining two or more sections. W6WRT's problem is more challenging if the boom wall thickness is 1/8"
Bob, I think in an old ARRL Handbook circa 1940-50's will have some details on a four sided, windmill style wooden structure. My buddy W9SKV and his father built one in the early 50's. It may not hav
John, I can only guess from your comment that you have not had any experience with a prop pitch motor used as a rotator. There are several reasons that one would use a prop pitch motor. One was cost,
