    Can you use 18" actuator on a 10ft dish if you only need to access 0°W - 100°W?

    Venture, Saginaw/Thomson, Von Weise. Venture looks like they have them ready to go. Saginaw has a configurator. Von Weise moved from TX to Mexico. Spoke to the owner a few years ago. They build actuators for solar/satellite on demand. We spoke about a group buy of 5-10. Nice guy. Long life...

    Can you use 18" actuator on a 10ft dish if you only need to access 0°W - 100°W?

    I'll pipe in. First. Good photos of your current setup will help a lot. You should also state the sensor type you might currently use. Reed, hall, optical, potentiometer? And. Skimping on actuator quality will only exercise the disposable income concept. AKA: buy once, cry once. Not saying that...

    Need help adjusting 4.5meter C-Band dish

    Dish Setup Data Elevation: 38.2° Azimuth (true): 216.6° Azimuth (magn.): 227.9° LNB Skew [?]: 27.7° Elevation would be best checked if you had a straight edge vertically across the dish face. Unless there is a place on the mount that is...

    Rusted LNB Arm

    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...

    Rusted LNB Arm

    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...

    Position keeps changing with new actuator

    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...

    Position keeps changing with new actuator

    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...

    Position keeps changing with new actuator

    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...

    Repurposing broken actuators

    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...

    Polar vs Az/El Mount

    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...

    Polar vs Az/El Mount

    ...moon is now higher in the sky and has moved to the right in the sky. So you turn your head right to look right at it. I prescribe another beer....*pssssssht*. You only had to move it to the right. No up and down needed. Right? Besides getting up to take a squirt here and there. All you need...

    Actuator Problem

    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...

    Parabolics East H to H motor

    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...

    5G Interference on all Transponders

    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...

    Troubleshooting AFN Broadcast Reception on 4.5 Meter Dish

    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...

    Troubleshooting AFN Broadcast Reception on 4.5 Meter Dish

    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...

    Troubleshooting AFN Broadcast Reception on 4.5 Meter Dish

    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...

    Troubleshooting AFN Broadcast Reception on 4.5 Meter Dish

    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...

    Troubleshooting AFN Broadcast Reception on 4.5 Meter Dish

    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...
