How do you match it? I assume it is a full wave length (length = 1005/MHz) loop. A Delta Loop requires a matching network and in some cases the matching network is frequency dependent, e.g. a quarter
The T2X wedge binding is SOP (standard operating procedure). I use a Green Heron and even with its special software that delays the rotation from the wedge brake retract (300 milliseconds) and then i
"I definitely cannot get to whatever ground rod they may have put below grade without busting concrete." Then how do you know that it is even grounded? I would contend that covering the ground rod wh
Unfortunately through the grounding panel at the entrance is on the opposite side of the house from the power entrance. Roger (K8RI) I have the same problem and have no desire to move the power panel
I agree that the controller is probably toast. I would highly recommend a Green Heron RT-21. It uses TVS devices which saved my controller with a recent near field lightning hit (at the expense of th
The Green Heron controller has TVS diodes across all of the rotator lines except the brake and start capacitor lines. I suspect they would blow (68 V and 15 V) long before the MOV's. The TVS diodes s
Jim has hit the nail on the head. Another area that all of the major insurance carriers departed from after Hurricane Ike was the Texas coast (one mile from any body of water was the State Farm cance
Here are the parameters I use on my T2X SETUP Parameters Offset = 180 Delays = 4 (4 seconds with an allowable range of 1 to 6) Min Speed = 2 (overrode in the AC MOTOR max speed setting which starts a
As part of a tower replacement project, a possible plan is to remove the existing foundation in one piece using an infinitely sized crane attached to the tower anchor bolts. The pad is 6.5 x 6.5 X 4
The AN Wireless Tower foundation as I view is a specialized pad since all three legs are attached to a contiguous piece of concrete. I calculate that it would be at least 10 cu yards of concrete for
Plus the Green Heron uses transient-voltage-suppression (TVS) diodes which blow after an event (> 20V on two lines >80V on two lines). The diodes blow (self-destruct) so they are easy to identify and
Agree, disconnecting everything is the only reasonable means of protection. If your radio equipment is hooked to a power outlet and/or a computer, those connections will have to be disconnected also
Any thoughts on which is better for a full wave delta loop antenna - a 2:1 Balun or a quarter-wave coax stub (Q-Section) for matching a 80 meter delta loop antenna (Z from 100 ohms to 50 ohms transmi
Andrew Corporation (http://www/andrew.com) which is now CommScope had some very good on-line training documentation regarding hardline and the associated connectors. It was very labor intensive findi
The Rohn SSV self-supporting tower series is a 400 foot tower that can be custom designed to accommodate any load at any height (obviously a reasonable load at less than 400 feet). Rohn will do (at l
Doubt if this is correct forum but I need some assistance. I've lost two desktop computers and some radio equipment in the last three years having experienced near-field lightning damage (hits ~ 1/4
Actually I received a lot of off-line suggestions. I appreciate the effort by a number of kindly amateurs. There seemed to be two common threads to the comments. One along your line of going back and
Something is amiss and I suspect it is charges for neophytes versus established businesses. I've shipped complete towers from Rohn (SSV 20 foot sections totaling 100 feet >> 400 lbs) for never more t
both of my two TB3 thrust bearings seems to be binding. All TX2 Tailtwister rotator electrical data measured from the ground matches my baseline (resistance), I can hear and feel the brake release a
Rohn SSV towers are worth the cost if you don't want to hassle with a tower for periods of 30 years and desire to avoid having it fall down (lol). The SSV series is a 400 foot tower where specific 20
