[TowerTalk] Rotor Cabling Query

[Wayne Kline]

The  TeleX   HiGain   TX2  brakle wedge issue is well documented… a redisinged  lowere bell and not square but tapered  brake wedge solved that issue.
As with ALL TeleX/CDE/Hi Gain rotors the quick release  brake  lever  can be distarious  especially with any  antenna with  rotating Mass.

A well documented fix is a home brew ( let google  to the rescue ) or ther have been commercial BRAKE  delay circuits for this family of  rotators .

As for cabeling my longest run (just took the 40 meter tower down )  was 700 ft plus 110 up the tower. This was on a Tail Twister . I used a pair of UF 12ga wires  to the base of the tower  Yes just 6 wires…..  I put the motor starting Cap at the base of the tower  and then 8 wires up the tower2X16 6X 20 Ga.

On my 15 meter tower the run to the top is 880 ft.  I used 14GA UF two runs and then the HD  2/16 6/20 ga up the tower with the  starting cap at  the base of the tower.   To over come the IR/loss   V drop I  mounted a  12 V transformer on the rear  of the control box   to increase  the volatage    This on a Ham 4
Has been that way since 1990

And, if you disconnect the brake wire, the brake will never release!

No, Hy-Gain uses a spur gear drive which offers very little resistance
to turning so they need a wedge to maintain position.

So will the HyGain Tailtwister hold securely with no creeping if I
disconnect  the brake wire ?   I have had the typical stuck brake
scenario with my old Tail Twisters in the past and I like the
idea of not using the brake circuit if possible. I always let it coast
to a stop anyway.    I have a new TailTwister replacement going up in
a couple of weeks.
