wilspin, ya might be able to use an infrared to uhf remote / extender??
solidsignal has something generic that looks like it might work.

NextGen Invisible Multi-Room Remote Extender Frequency 418 (LRRX418)

Model: LRRX418
Availability: In Stock

Works with any IR (Infared Remote) controlled device - Stereo, TV, Cable, Satellite, DVD Player or VCR
Extra RF Transmitter / Batteries are available, see link
Works with any remote that takes a AA or AAA battery
Transmitters with blue writing are for 433 Mhz frequency, 418 Mhz units are red
USB Battery Charger Available
New High Speed Chipset
UL Listed Batteries
Energy Efficient Power Supply
The Only Difference Between the 433 and 418 are the operating frequencies, allowing you to use two systems in the same home without interference
*The frequencies do not denote performance, nor do they have anything to do with the compatibility of the units as they are exactly the same differing in frequencies only so that two systems may be used in the same home without interfering with each other
Control satellite and cable receivers from another room!
Includes 2 rechargeable batteries, charger, transmitter, and remote signal receiver. Does not include remote control.
Great for hiding away messy wiring and oversized Audio Video receivers
Control A/V components up to 100+ feet
The LRRX ONLY works with IR remotes; it is not compatible with any remotes that are already using rf or uhf functionality
The Newer LRRX Models with the Plus next to the Mhz notation are compatible with A&tt Uverse equipment. The older models do not have the plus symbol.

Just wondering if you know what the difference is between Eagle Aspen ROTR100 and Eagle Aspen500065-1 ? They look very similar. The second one is more expensive? Thx

They're the same thing. Someone just copied the PBI SKU off the box instead of the model number. See the PBI sell-sheet at http://www.eagleaspen.com/admin/product/fujian/file_251.pdf Look near the bottom, left side.

The internet, being filled with content copiers and otherwise lazy site operators, simply has propagated the error.

Remote Extender- Radio Shack also has one for about $30. It works for the rotor, as well as a remote-controlled A-B switch (also from Radio Shack). I use it so that the rotor and switch can be operated from the living room and the bedroom.

Ok was not thinking that way. But does that mean I cannot see the display and therefore don’t know where it’s pointing? Right now I can swap cables in the basement and have it in the room with the remote as is. I want to eliminate the cable swap. Is there no passive 3 way joiner?

I am about to pick up a rotor this weekend. I can't seem to find the CM 9521 in stock anywhere and it seems like there is a lot of problems with it. How about the Yaesu G-800SA or Hy-Gain AR40? It seems quite pricey and am not sure if this is overkill for what I will use it for. I have the CM 4228HD and VIP-306SR? Any Recommendations? Thanks.

The VIP has a pretty substantial boom length. The Yaesu and Hy-Gain rotors are more robust than the 9521 and I would be inclined to use either of them than the Channel Master.

My 9521 has started it's slow down as the weather cools. I’ve got to remember not to turn it when below 0c in case IT GETS STUCK. I usually have to go outside now to be sure where it’s pointing. The cooler it is the slower it goes unless it’s a long run as it speeds up near the end and if you move it again. I guess it warms up. The Rotr100 has rock solid performance. Zero sync operations so far.
Score so far;
CM 0 EA 10

After a month of testing I have taken down the test tower and prepared the final location to receive it. I have added a boot to keep the weather out of my custom thrust bearing. It is a universal vent stack flashing from Home-Depot where U cut the opening to size. It covers the top of the tower nicely. Pic will be in my profile by the weekend. As it is at the south end of my lot where there are no trees for at least a kilo. I had to trench to the house and put the coax in a conduit.

Willspin,

Have you had any issues with the Eagle rotor and the CM amp (7777)? Do you know where you found the power specs for that amp? I too am in the same position of looking for a rotor. Did you try any other type(s) of rotor before getting the Eagle? Thanks.

You can find more details on the Eagle Aspen rotator, including specs, at the company's website (http://www.eagleaspen.com/).

Jase88, I was looking for specs on the CM amp. The Eagle Rotor has a limit on the pre-amp Power of 18VDC at up to 80 ma.

Looking through this thread there doesn't seem to be any rotors between the 2 extremes. The CM rotors doesn't rate well/cheap and the Yaesu or Hy-Gain are durable/hundreds of dollars. Surprising that someone hassn't filled in that niche.

I ran separate cables to avoid any pre amp issues. Tried the CM 9521, was VERY disappointed.

threeflags, the CM7777 power inserter injects 18VDC for the amp--same as the Eagle Aspen. The EA rotator system is apparently intelligent enough to know when a preamp is used, and provides continuous power when configured as such. Power is switched off when not in use otherwise.

Yaesu and Hy-Gain weren't designed for the TV viewing market. They are built for amateur radio...where the antenna beams can often be considerably larger than your typical TV antenna. They certainly work very well for TV antennae. But for your typical budget-conscious antenna TV viewer, they're overkill.

Having said that, Hy-Gain does sell modestly-priced yet excellent rotators like the AR-40 ($349.95 USD).

I've said this before: The re-sale market on HAM/amateur radio rotators is the place to look. HAM operators tend to be obsessive about maintaining their equipment, so you'll always get good value buying used. And you often get extras like the control cable thrown into the deal. And should you require parts, Hy-Gain (and presumably Yaesu) sell every last item you'd ever need for their equipment.

I have a Hy-Gain HAM V rotator that has a manufacture date of 1974 stamped on it. Still working perfectly today, and in over two years of service on my current tower, has never straying more than 1° out of alignment, nor failed once--even when covered with ice, snow and subjected to extreme cold and heat.

Thanks for the answers ... when you got your rotor did you look at a Radio Club for it from the usual suspects (ebay and Craigslist)?

Jase88

Those are good resources. Though I found mine on Kijiji. The key is to look beyond your local area, as rotators are such a niche item--and patience, as they don't come up for sale very often. I ended up finding mine in Hamilton, which isn't too far from Kitchener.

If you must buy new, the good news is that Wilspin has had some good experiences with the Eagle Aspen. And, as mentioned, the AR-40 is an excellent solution that's not too expensive.

Google "Ontario Swap Shop" and see the listings there. Ham rotors pop up from time to time.

i wasn't sure where to post this so I cross posted in a couple places, hope that's ok.

I have a 9521 rotor, when I connect it to my antenna it appears fine until I try to use it, than it just clicks like crazy, a really fast ticking and the display goes kind of wonky. When I disconnect it from the antenna rotor wire it works perfectly fine. So it seems it doesn't work under load but otherwise it's fine?

Any ideas at all would be greatly appreciated.

Thanks all,

Matt

The control box is making the noise, or the rotor itself?

Are you certain the connections are on the correct circuit?!
