My SteppIR is exhibiting high SWR at all frequencies. Varying the length of the driven element does not affect it. If I plug only the center conductor of the coax into the rig the noise level is much
return spring is broken and the tape is not moving. Most likely a big mess of it snaked up in the housing. Disconnecting the braid is just giving you some random length wire antenna better at pickin
Yep Martin is right. Mike, One way to figure it out is, if the motor movement sound can be heard from the ground level, park someone outside and turn the motors. Any odd noise, you will know what has
I don't understand the logic here. If the SWR goes high on all bands, why wouldn't it be logical first to check for water ingress in a connector, or some similar simple failure, before assuming a maj
Shorted/open coax feed line? Happy hunting! 73, Gerald K5GW In a message dated 5/5/2011 6:10:57 A.M. Central Daylight Time, nf4l@nf4l.com writes: My SteppIR is exhibiting high SWR at all frequencies.
Like I said, I have little specific knowledge here, specifically 5 SteppIR failures, 3 were drive shaft failures, 1 a corroded return spring and 1 a bad connector. But they are the only 5 SteppIR ant
Hi Pete, The water in the coax can be a suspect, but i assume most hams use some sort of sealant at the junction and hence trouble shooting the EHUs would be yet another logical step. At any rate, if
Thanks, Martin and Krishna. The EHU is brand new, it replaced one that had a tape snarl. While a possibility, I think the probability is low....... maybe. 73, Mike ___________________________________

I have a 4L SteppIR. I'd guess a bad coax or something similar too, but you can easily check the EHUs from your shack with an ohmmeter, and you can measure the voltage output of the controller. I use
GM, Am just finishing up replacing my control cable to my SteppIR 3el. Symptoms were High SWR all bands. PROBLEM - mice in underground conduit chewed the cable, S L O W L Y. Drove us up the wall. 73,
Thanks, Jim. The EHU's ohm OK, I have 2 bad driver chips in the controller, 2nd director and reflector. My Ameritron RCS-12 switch handles 6, but not 60. Which is OK with me. 73, Mike _______________
It sounds like your coax is not connected to the driven element. It could be a dead balan, bad connection or that the DE is fully retracted (if that's possible with a SteppIR). GL John KK9A My SteppI
Thanks, John - I'm going with the coax theory for now. It's a new motor and balun, so hopefully that's OK. 73, Mike NF4L _______________________________________________ ______________________________
Mike, When I connect only the center pin of any coax fed antenna I usually get more noise since the cox becomes an antenna and this includes the SteppIR. Since its a new motor and balum did you do a

I figured as much. But just to keep on top of thing, I had to make sure I wasn't missing out on the latest thing. Sent from my Verizon Wireless BlackBerry --Original Message-- From: w4lde <rwalters@n
Thanks Ron - The motor on the driven works fine, at least it did on the ground. One other anomaly is that on the ground an analyzer showed a dip at around 6.5 Mhz with the antenna set at 7.150 Mhz, w
