I have been searching these forums and can't find a definitive answer on a simple question. How long can you run solid copper conductor RG6 cable without signal loss? I have a big tree problem and I will need about 120-150 feet total (dish to receiver) of cable to get around the trees. And btw chainsaw not an option

should be no issue with solid copper. I have run 275' without issues for a LOS.
Some will recommend amps/lockers. They are overkill for 150ft.

My install is a Slimline AU9 if that matters.

Like Mertzen said, if you have a high-quality solid copper cable you shouldnt encounter any problems at those lengths....

How would you know if you were having a problem? What would be a symptom of that type of issue?

I ran 2 cables of RG6 Quad from my Zinwell multiswitch to my family room which is the length of the house 70'. The dish is mounted another 25' outside the house on a pole. I have had no problems receiving HD programming except low numbers on 103s. I am in Chicago locals.

The symptoms would either be DC voltage loss that would prevent the switch from switching, so you'd only see odd or even TPs, or you'd have signal loss, which would affect the higher frequencies more, so the high-numbered TPs would lose signal strength.

In reality, though, signal strength is almost never the problem; it's the voltage loss that causes the problem first.

Multiswitches are normally sent 13V for even TPs and 18V (really closer to 19V) for odds. If there is enough line loss that the 19V sent by the receiver falls below 16V or so, the switch will never get enough voltage to switch to the bank of odd-numbered TPs.

This is why longer runs require solid copper cable; there's less DC voltage loss with solid copper than with copper-clad steel cable.
