as per your thread-
"Ok, now for the bad news. There is no free ride with this single cable deal as I suspected. Their specs claim a loss of only 1db per device (2db total). Well, at certain frequencies that is true, but there are a few exceptions.
My measurements with a Spectrum Analyzer show a loss of -4.5db around 780MHz (ch65). There are also losses between 3 & 4db around the following frequencies; 493 (ch 17), 601 (ch 35-36), 675 (ch 47-48) & 710 MHz (ch 53-54).
This doesn't include the loss for each fitting in and out of the rotor & control box (probably around another 2 db total).
On the 3rd attachment, two vertical divisions from the left is 470 MHz and one division from the right is 806 MHZ which is the current UHF TV spectrum. As you can see the trace is anything from flat. I did the test twice checking the 'null' of the scope with just the jumpers in line, then with both units connected.
BUT, there is a easy solution; Run a separate cable (or wire since you don't need to use another coaxial cable for a control signal) as you have done in the past and solder it to a 'F' fitting at either end and run your downlead as before. Done!Ok, then what's the big deal? Repeated accuracy. "[/b]
This is the part i cant understand as I'm a newbie and this is the first time I've even istalled an antenna-ive put up an Antenna direct clear stream 4-which is really clear but directional-thats the reason i'm looking into a rotor and came across this forum -which piqued my interest in the eagle aspen - however couple of ?'s if u dont mind-how does this rotor function in the very cold as I'm in toronto and temp goes down sometimes as low as -35*c and how do i add the other cable as you described in bold
thanks for replying
