For towers under 50ft there is another solution...run a pipe down to the bottom of the tower and mount the rotor on the concrete pad. Easy access for maint. and if you want you can let the antennas s
Hi Folks, Has anyone figured out just what this tuner is made of? It has no electrical connections for power yet is it claimed to be automatic and yet it supposedly matches a wire or dipole to any fr
Jon, Pin bases can be used with guyed towers. The PIN base only has to keep the bottom of the tower from jumping around when the wind blows. Imagine a 40ft 25G tower guyed at 20ft. With the base rest
Pete, The spool you see on the mobile vans are actually PVC tubing and the coax runs inside the PVC. It gets heavy and the 58' mast now have a basket half way up to balance the weight...the newer van
Pre -coat the bolt with TREE PATCH ( a black substance with the consistancy of roofing tar). Let dry before installation. The tree won't know the difference. It's key to remember that most of the nur
Hi folks, I use Brand-REX style 1680 (UL) AWM copper braid. This is braid that comes in 3/4" and 1" sizes with a heavy duty vinyl coating that can easily be sealed at the ends. I've used it for my mo
Why are folks disconnecting the cap inside the control head? twice the capacitance isn't going to hurt anything as best I can tell. On air-conditioners when they install a start-up kit they are simpl
Hi Mike, That quote is a funny one too....because in the Tailtwister the brake relay and the motor are in series. So, doubling up on the wires benefits both the relay function and the rotor if there
Clarification, The power for the Brake solenoid and the motor are in parallel but both receive power from the brake switch on the control head. If the brake switch is not activated there is no power
George, You didn't tell us why you want this information??? I'm the Chief INFOSEC officer for Arlington County Gov.(USA) and I'm not going to tell you how many vans we have, plan to have, the size or
Leave the tower cranked down during storms...ground the coax at the top and botton sections. When it's cranked down use a jumper from the ground grid to the top section of tower. At the house use a b

Bob, You could solve your problem really fast if you had a MFJ 259 antenna analyzer. It's not clear whether what you have in the way or resonance or input impedance. At 13.1mhz you have your 1:1 50oh
Don't make it to complicated... When you are making your antenna comparisons you've got to de-tune the antenna that isn't not in use or it will act as a parasitic element and you won't have a clear i
Hey, thanks I may try that out...I'm going to build a second system and run the two of them in phase... Those readings of course are from on air "S" meter reports ... love the way AGC pumps up the si
