I would almost guarantee that the others aren't far off from rotting through. Especially if there are no weep holes drilled at the lowest spot on them. EMT conduit is engineered for outdoor use and is thin walled but rigid enough to just fabricate new arms. Sleeving them would be okay if you...

I'd get some conduit and duplicate a good arm. Grab a spray can of etching primer and spray inside the new tube before you smash the ends shut. Spray enough to let it pool up and slosh it around inside. A vice would be nice. Or a couple of boards and a hammer to sandwich it in. Probably check...

Well holee-molee. There's your problem, Mister. All wires running together in the same cable. No bwayno. The sensor wires always at least have a shield wrapped around them if they are in the same cable. No amount of twisting and separating will fix that. The sensor wires in the same sheath are...

Don't be brand worthy. Superjack clones are rampant. I bought one from tek. It lasted about 2 years and I paid dearly for it. The gears ate themselves up. Poor weather sealing on the motor. Usual periodic teardowns. BTW I live in the North with nasty winters. If you got X years out of one then...

Yes. A 0.1uF disc capacitor. Not electrolytic. Across the motor terminals can help reduce some motor hash that may cause false triggers. Extra counts would be an indication that motor noise is inducing to the sensor wires. But it could go both ways I guess. I would be very interested in seeing...

12 volt to 24 or 36 volt conversion is easy. An ebay boost converter, search nearest first, with enough wattage could handle that. A reversing switch. Easy. What would worry me would be using an actuator for something subject to impact. Like to angle a snow blade. Look at your tube construction...

Where I live I think 5G interference will probably never be a thing. So, interested in hearing the others chime in. If you're a good fabricator you should do good in this hobby. So many think they can flop a dish up or bring one out of mothballs and get reception in a jif. Aint so. My...

Boy. Imma' talking 'bout the good ole You-Ess-of-A. Top of the food chain.

Ahh. The curious noobs. And great questions. May I? Also why would use actuators? Is that only if you want to track multiple satellites on one reciever? If I plan to just point the dish at one satellite, couldnt I just fix the mount in place and call it a day? Exactly. An actuator on a polar...

Could be worn motor brushes. Or worse. A flaky reduction gear. 2-12V automotive side marker bulbs in series on the motor terminals would be an easy way to see if the motor draws steady current. But you said you swapped receivers. You don't really have to reprogram the sats. if you decouple the...

The motor housing inner diameter and magnet thickness and dimensions would help. Magnets, I have. The corner posts must be riveted over. Carefully center drilled would allow the gear train to come apart. Accurate center drilling of the posts. Tapping them. Countersinking the gear plate. And...

Vacuum deposition, sputtering. I never found a metallic paint that had any electrical conductivity. Window screening. Worked in a pager/cell phone repair shop with triple mesh screen rooms grounded with earth rods. That made the room 100% rf "quiet". Hams use antennas tuned for specific...

Aiii capn', But never do the math and slap it there and call it a day. 1/4" in or out from that will make or break your day. Always peak signal and balance skew. Polorotors made skew a day at the beach. Right now I'm thinking it could be a slab/skewathon. Maybe, maybe not because using post #14...

Any chance you have tried changing the angle of the dielectric slab in the throat? A little at a time to see what happens? And the depth that it sits in the throat? This is interesting. Especially post #5 Slab And a few tips on depolarizer tweaking. Slabification and such For one reason or...

Didn't hear back yet. Looking over things that may be a bit "blurry" or fuzzy. The very end of the feed throat will always be tuned for highest signal strength. Just like a camera with a telephoto lens and lens hood. On a tripod the lens would be in sharp focus on the subject and never move at...

I just have hands on experience. Since most received transponders in the CONUS are linear. Circular polarization for me is just when experimenting with the fringe satellites over the Atlantic. But. I see a couple of things that lit up the old light bulb. Your installer got you a signal...

I see something that may or may not be a problem. But playing around may increase your expected performance. If in fact your feed is focused for the best possible signal. The throat is very close to the scalar surface plane. If I were you I would pull the scalar mount and bolt it on top of the...

Pull the lock bolt. Heat 'er up a bit. Feed it as much blaster as it will take. Tap it with a hammer. Tomorrow do it again. And again like Groundhog Day. Or take it off the dish and fashion up a tub to put it in and look up "Rusty tank electrolysis" on the 'tube.

You haven't mentioned if you've tried moving the lnb in and out to get better focus. And be sure it's aimed at the dead center of the dish before peaking initial signal.

Let's get a visualization going on here. "At 91w, pulling up on the dish causes the signal to decrease. There is no change if I press down on the dish." Looks like you have to lower your elevation or declination a touch. A hint to assure that the feed is indeed aimed at the dead center of the...

Oh. To the OP and all the rest of you guys. Don't take it wrong. Much as I cannot get PBS. Because I haven't subbed to cable or sat in years. PBS and a very few others on ku are okay. But honestly me personally am steered on c band 99% of the time. If I found content on ku as satisfying I would...

Easy and cheap and you won't be too bummed out when you find not much worth watching on ku.

Could I try to revive this thread? I've been brainstorming so much my head hurts. Since Brian discontinued the ASC-1 dish movers are sparse out there. Ones which accept a DISEqC go-to message from a receiver. I've contacted NXP for info. implementing one of their dev. boards to make a mover...
