Yes crown controls actually made the rotor for channel master,some radioshack archerotors,home hardware venture rotors,canadiantire pulser rotors.

I think Channel Master makes one that will move the antenna automatically depending on what channel is selected. It's the 9521 control box. You can purchase it with and w/o a rotor.
You aim the antenna where you want it and then program a channel number into the box. The same problem goes with any of these non-feedback rotors, you don't have the accruacy of a rotor with position feedback. If you have a station that is very critical, you will have the probablity of having to 'tweak' the position after you recall the channel number.

The Eagle Aspen rotor has the channel memory and the feedback. ;)

Help guys,

I put up a CM 306 VIP and a CM 4228 on a 64 ft tower and now when i rotate the heads, the rotor takes it to the right spot but it has alot of play on both sides, and when its windy, the heads move about two inches either way and the UHF digital fluctuates. Any thoughts? I'm thinking of removing the VIP 306 altogether with the little analog their is and put up a second CM 4228 (stack). This may redouce the chances of the play in the rotor.

Any suggestions will be welcomed and appreciated.

chungdokwan, Yaesu rotors have a terrific reputation but they need to be scaled to the expected load in order for their braking to work properly, so maybe that's the problem. I'm thinking that your rotor will be fine without your 306 up there. It will probably be fine with stacked CM4228s as well.

If you look in the operator's manual it has a page full of formulae to tell whether your rotor can handle the antenna load. Here's the manual in PDF form if you need it:

If you can get a good trade-in amount for the Yaesu 800 you might want to think about one of their stronger models to handle a stacked CM4228 array and also your 306 up there with it.

I don't really understand the play issue with the G-800. I have used a G-450 for an amateur radio antenna which has a higher windload (8' boom with 17' elements; 3.3 sq-ft wind area) and have never had any play issues.

Is there any data on the VIP? Windload, etc.? I know it's phsically not that heavy.

The manual file left out one spec that applies to this issue.The backlash spec is +-2deg,causing the slop.It's just the nature of the beast.I've had three of them and they are all the same.The 450 is not quite as bad.Love the rotors otherwise.The variable(slow) speed on the 800DXA comes in handy on my UHF Band-A Quad stack as the beamwidth is extremely tight.In really windy situations the backlash can be a problem on very weak signals.

The 800 will handle several large TV antennas with a K-factor of 1300.

Here's a pic of my UHF SuperStack with the 800DXA mounted inside the Heights 55ft Crank-up.

Interesting info. So would something like a Ham-IV with a wedge brake be any better for "slop"?

I'm not familiar with the Hygain rotors,so can't answer that.I hear the worm gear type have very little to no backlash(ie Create,etc),but are very expensive.Actually,the CM rotor has less slop,and will turn one big VHF and a UHF,especially if it's mounted inside a tower or properly set up using a rotor mast support bearing.I have one 30ft swing-up mast using the support bearing,turning an FM antenna now,but used it to turn two 13ft Highbanders spread 6ft on a H-frame for about 3 years with no problem.Pic;

welcome hoosierDXer:

"THump" !
That was the sound of my jaw hitting my keyboard when I saw the pics of your rigs. :cool:

Thanks for posting

hoosierdxer, how many channels can you get with your antenna? Wouldn't it be cheaper if you subscribe to cable or satellite?

The big antennas are for weak signal(DX).I regularly pick up most digitals from four adjacent markets,plus a dish for Sat programming.

Current DTV Log is 312 stations from 23 states.Still looking for something from CA,but haven't had a good opening since 04.Maybe someday!

Wow! Where are you hoosierdxer?

Oh, I have always been more of a CFL type guy until they decided to throw away half their audience and let TSN broadcast all the games.

That's close.They deflated the Hoosierdome and they are now in their new digs,Lucas Oil Stadium,the one with the big sunroof -:)

I posted here (http://www.digitalhome.ca/forum/showpost.php?p=824485&postcount=628) regarding how to pre-wire my new house for OTA. The walls aren't yet closed, so I'm pulling various wires this week. Stampeder was kind enough to clarify reqs for coax, but he suggested I try here for what I need for a potential rotor. Without knowing which rotor I will go with yet, is it possible to prewire for most/all rotors in some standard way?

You could certainly pre-wire with something like thermostat wire (5-conductor) or underground sprinkler cable (4-6 wire depending on product). Most tv rotors require 3- or 4-conductor cable. The bigger amateur radio ones require more (Yaesu needs 5; I don't know about Hy-Gain).

I'd be home running everything to the utility room before making my way back to the living room if needed. Is this a practical approach for rotor control?

Rotor wire needs to be run directly to where the controller will be located. The controller supplies the power and plugs into a standard outlet.

Personally I use a combo coax/phone jack wall plate. I pass the rotor wire through the opening where the phone plug would have gone. It required a slight destructive mod to the back of the plate.
I tried wiring the rotor wire to the plates phone jack connectors, then using an old phone cord to wire to the controller, but the phone cord wires and connections didn't pass enough juice to run the rotor.

Hi everyone,

Can anyone tell me if this is a channel master or what brand it might actually be?

I found a reference to another model that was a channel master. I'm thinking this is a good deal but it does not come with the digital box or remote, just the directional dial controller.

Thanks.

That one is a Nexxtech brand rotor manufactured in China by Orbyx. You can see several posts about it by putting that product number into the Search This Thread tool to the upper right. :)
