DX Engineering sells very good rotor cable, as does Davis RF.
And there's always eBay or Amazon.....

If it's a fairly short run, maybe CAT-5? If it's a little longer run, maybe twist 4 pairs and run a CAT-5 for each rotator?

Any good suggestions for cheap 8 conductor rotor cable?
I'm gonna use two of the alliance U-110 rotors, and they are 4 conductor rotors. soooo, need 8.

Hi Joe,
Vertical works fine but man made noise is mostly vertically polarised so you will get a bit more of that. With horizontal, you have more problems with ground reflection so you get more fading.
Depending on how big your metal cross boom is you will have no problems on 2M. On 70CMs the metal boom upsets the gain/radiation pattern. I tried this with a 2"" cross boom and it didn't work well at all. A shorter yagi, end mounted worked much better.

Weather is nice, Time to put up antennas.
Now I know most like to go CP, But I'm on a limited budget. So it will need to be a traditional linearly polarity yagi,
Of course I can mount them vertically or horizontally polarized. And if it was just one band, is there ny preference to vert or horiz?
I don't see any, except from the man made noise issue when on low elevations.
is there any best polarity?
I'm planning on a side by side 2 meter and 70 cm set up 2 meter vertically polarized on one end of a cros boom, and the same on the other side but 70 cm.
This way I can get away with using a metal cross boom.
Thoughts?
