counterpoise the radials all radiate substantial less problem that is? Or did you think I want the radials to radiate. I kinda liken each element as a half wave dipole with one end of the dipole in

Specifically, how are the vertical radiators isolated from the 1/4 wave 75 ohm feeders? There isn't enough spare coax to wind a choke. Buried 3/4 wave feeders and a coax choke? How many turns is "eno
Wilson rates this 3 section tubular tower for 2 square feet of antenna at 61 feet. The tower itself extends to 52 feet so for the 61 feet you would add 9' of 2" mast. At 53 feet the tower is rated at
Some towers, expecially crank-ups, have a sleeve at the top of the tower that will hold the mast vertical when the rotator is removed. de Paul, W8AEF Hello: I've been monitoring this interesting thre
I suggest you use an antenna analyzer and find out where the antenna will work. Then proceed from there to either make adjustments or return it to Hustler. de Paul, W8AEF Hope someone can figure this
My management experience indicates crap starts at the top and works down (along with BPL). Amateur radio is supposed to be above politics but BPL is politics. Witness how quick the FCC and NTIA chang
I agree. de Paul, W8AEF Craig: Tower Rule of Thumb: You can never install too big a conduit. (This is similar to: You can never have too many antennas.) -- Outgoing mail is certified Virus Free. Chec
Move to Arizona <ear-to-ear grin>. de Paul, W8AEF from sunny Arizona What is the best way (IF any) to keep your tower from icing in the winter??? You Canadian boys found a way to prevent this yet?? T
I always unfastened the far ends of my inverted V's to remove the side pull from the tower, especially when cranking it up. de Paul, W8AEF I am planning to put in a sloper for 80 meters. My tower is
As I recall Force 12 shipped a bunch of C4XL's with wrong 15m driven elements due to a laser printer mis-printing a dimension on the drawing. Of course to get this information you have to call and if
I always go to http://www.mods.dk/ to check for manuals. Operator manuals are easy to find as they are on what I call the first layer. Many service manuals are there also but you have to really want
If the tower sections do not taper from bottom to top you could cut the bent section out and splice the remaining parts together. I did that on an Aluma tower and the splice worked very well. de Paul
The destructions that came with my Comtek phasing box(s) suggest that each element be cut about 5% long, the array erected and then observe the frequency that the minimum amount of power is dumped in
Against Tri-ex's recommendation I did climb my LM-470 to secure the feed lines and control lines to each standoff. I did jam a 2x4 through the crossbars at the top of each tower section with the idea
My experience indicates you have a sticking brake wedge. My Ham M had a V shaped wedge and the brake never stuck. Several years ago I rebuilt the rotator and for some reason replaced the wedge with t
I suggest you check the zener diode in the bias circuit - sounds like it has gone open. de Paul, W8AEF Hello All, Merry Xmass! Not sure if my request is right for this Reflector but I'm looking for V
Hooray for us! I turn 67 this month. I have found that working on the tower after dark helps the vertigo thingy also, and sharpens the (be careful) senses. de Paul, W8AEF Mike et al, Age here is 69 1
