Eagle Aspen ROTR100 / Juice preamp question
Would the Eagle Aspen ROTR100 http://www.solidsignal.com/pview.asp?p=rotr100
be compatible with the Antennas Direct Juice preamp for a single coax feed? Also does this limit signal to any substantial degree? |
It mentions the optional ability to drive a preamp.
It also mentions 1db insertion loss each for the motor and the controller. 2 db doesn't seem like much, until you need an extra 1 db. It maybe OK for some, but I have always believed in keeping components as isolated as possible. |

The ROTR100's capability to supply power to a preamp via the 1-wire scheme was limited to preamps that would run off ~17 volts DC at < 80 mA. Our PA18 met those qualifications but I could never get a single ROTR100 from half a dozen samples to actually work correctly in that mode. Neither the Juice nor its predecessor, the CPA19, would have any chance to function in this mode as both have much higher current requirements (110-130 mA typically). Quote:

In any event, the only thing in the signal path in either unit is a small value capacitor that passes the RF signals but blocks DC. There's not much you can do about it if you're not using an amp but to accept that you'll have a bit more insertion loss, exactly the same as if you'd had a longer coax or some other attenuation etc with or without an amp. You STILL have to do your homework and the math to calculate the insertion loss either way for any situation where you're working close to the reception noise floor. If you're in a strong signal area, it doesn't matter as there's enough signal margin to tolerate the small amount of additional loss. I tested the IL for the ROTR100 a few years ago but haven't revisited that subject since. Since the product is pretty much dead or not available, it's a moot point as I see it. |

You'll have to pick from the following options since you have one already:
1. Run with no amp and see what happens. 2. Run a second cable. 3. Try and find an old amp that actually works with your rotor and still works in the new location without causing new issues of its own. Good luck! |

I'm thinking about using a wall mount over chimmy given the location of the line into the house are ROHN worth the extra cost over other brands? What are height limitations for this sort of mount? Would any of the telescoping masts work?
|
Rohn is a good quality brand.
http://www.3starinc.com/telescopic_masts_and_more.html You could use mast sections with wall brackets. Guy wires are needed if you go higher than 10 feet above the highest support point. http://forum.tvfool.com/showthread.php?t=15712&page=2 |
