I'm planning the install for a 3-el SteppIR (w/6M element) that requires a cable run of about 400 ft. (no 30M/40M elements -- I've already got dipoles at 100 ft). I'll be doing a lot of contesting, s
I believe the Alfa Spid is easy to set up for very long cable runs (without using heroic size wire). Check with the guys in Canada who sell it. I have been using one of these with my 4 element SteppI
Hi Jim, You could probably use any rotator with DC motor. I use a Prosistel PST2051 with a 600 ft. cable run. The connection to the transformer in the control box just needs to get rerouted to a high
I would think the opposite would be true, you could use fairly thin gauge wire if it were and AC Motor. Mike Hi Jim, You could probably use any rotator with DC motor. I use a Prosistel PST2051 with a
Almost any of the larger rotors will work for you if you have heavy enough wire running to it. I have a Tailtwister mounted on a 150 foot tower which is located about 475 feet from the station. I use
What about putting something like a Green Heron at the base of the tower, and then just send the RS232 commands to it. I know you're not looking for computer control, but it's putting the power stage
Almost any rotator of sufficient size to turn the antenna with a potentiometer will suit your needs if you use a large enough cable to minimize voltage drop. My last station had cable runs well over
Jim, I'm no expert but I do have a 3 el SteppIR and a cable run of 350 ft. Perhaps my experiences will be helpful. For the SteppIR control I use their 33 Volt power supply with the control cable I bo
Hi John, Thanks. I'm concerned too. FWIW, I am disgusted with the mfrs of all of these products, including SteppIR, for not publishing specifications for what is essentially a simple Ohm's law proble
SteppIR makes a high voltage supply for long cable runs. And the cable [is] wound with pairs, they give the ohm-out in the book and it is on line. For a rotator, I used the Alpha Spid and a Green Her
Why? Please explain. My PST2051 rotators all run through CAT5 computer cables. 73 Peter I would think the opposite would be true, you could use fairly thin gauge wire if it were and AC Motor. Mike --
Jim, I currently have four Alfa Spids in use here. The shortest cable run is 400 feet, the longest almost 600 feet. Four wire control helps cut rotor cable costs. I?ve never had issues with the pulse
that's the difference between amateur radio (essentially consumer) gear and professional. Amateur gear makes the assumption that you're going to plug and play, and not do any engineering. Complicated
Thanks for all the advice. 73, Jim K9YC _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.co
