Why is everything turning on the mast? Does't the Ele rotator do Azi also?

Hi Alex. We printed your 45 deg mount, and are going to use an Alaskan Arrow antenna with it. I'm going to try to use a PVC (Schedule 40) cross boom as the Alaskan is longer/heavier, so I'd like to have it balanced. Hope I can fit the mount inside a 1in (Inside diameter) PVC pipe. Haven't gotten that yet. For now, not going to have RHCP but will look into how you did yours.

What a cool idea, I'm a little wary of those CF PETG mounts due to the leverage on them, careful in windy conditions. Best part about 3D printing is you can easily make spares

Hi Alex, Great video, I am considering building a K3NG antenna positioner but instead of using traditional antenna rotators with potentiometer feedback I want to use mems magnetometer and accelerometers for position feedback which the K3NG software does support. I wonder if you have an opinion on the viability of using this type of position feedback, in particular the angular accuracy of these devices.
@va3ase 4 ай бұрын
Hi I'm glad you enjoyed the video. You are correct about K3NG supporting an HMC5883L digital (magnetic) compass and ADXL345 accelerometer for feedback. I have experimented with these sensors a bit and was able to get them working on the bench, though I haven't tried mounting them to antennas for real use. It has been a minute since I looked at the datasheets but I believe they claimed 1-2° accuracy / repeatability (or less). That's more than enough when your typical antenna's radiation pattern is >20° wide. The potentiometer feedback from the G-5500 is very crude and I wouldn't trust it to be accurate or repeatable to less than 5°. It's probably worse than that actually, but still fine for most applications, only becoming an issue with very high gain and narrow beamwidth antennas. Keep in mind the sensors (especially the compass) will need to be mounted away from motors and power cables to avoid magnetic interference. This is the main reason I never finished testing them. It's not a big deal, just requires some planning. I hope it works out for you!

I LITERALLY just bought one of the Arrow antennas to use for Field Day! 🙂 - And like you, I've beem running fixed polarization (vertical in my case) for satellite operation, with the resultant fading issues you mentioned, so I'm VERY interested in seeing how your project turns out, I may do the same! 73, Tom WA1LBK

Thanks Alex, really interesting video. I've dabbled with satellites with a fixed white stick antenna and managed to work a few passes using an FT-847 with Doppler control via the PC. I have an antenna interface for the Yaesu AZ/EZ mount but need to spend a little more time thinking about antennae but I really like what you have set up here with the polarisation options and the harnesses. It has been.a slow burner project - it got rudely interrupted by a project to set up for the QO-100 geostationary satellite which has been good fun, but I can feel the LEO satellite itch returning! Good luck with the field day, hope you manage to post some footage :) 73 de M0SNR

Alex, great job putting this together. I've been wanting to modify Arrow antennas much as you did for a few years. Some questions. 1) does it make any difference whether you drill the holes in front of the existing cross beams or behind? 2) I'm assuming you made a 90 degree phasing harness; any specific plan you used? 3) any unique problems you experienced reconfiguring the Arrow antennas? Thanks & 73! Jeff, WK3U

I'm putting together a g5500 right now and the EL moves with just finger pressure...is this normal? The az is locked solid but even mild back pressure from the cables causes it to move.
@va3ase 6 ай бұрын
No, the internal gears should prevent you from moving the AZ or EL rotors by hand. Make sure the mast is not slipping, it can be hard to clamp securely without crushing it.

Excellent? Where you using a circular polarization for this contact? I was thinking about building with just a circular polarization rather than switchable or fixed horizontal/vertical with a switch as some do. Have you ended up just using one setting over the others since yours is switchable? is circular the way to go for satellite to avoid switching?

Hi, i would recommend a counter balance weight on the antenna motor shaft! And a slow start stop function on the motor! This will increase the lifespan of the motor and gears a lot!! 😉👍 And it will also make it go a lot more smoother and more accurate!😁

How are you balancing the weight of your antennas? Looks like most of the weight is towards the front. I like the use of a ladder as a tripod. Do you think you will build a case for the original rotator equipment and to include all the new stuff?
