Here's my dilemma.  My shack would be best on one side of the house but the best place to run a wire dipole is on the opposite side.  If I were to run a dipole in this configuration, I'd have about 75 feet of coax running either from the outside, through the attic, down the opposite exterior wall and back into the house.  Option B would be to run it along the outside of the house passing multiple gutter downspouts, wires, etc.  Neither of which is ideal.

Another option would be to run a loop along my roof.  I'd have to measure but I should be close to 150' of wire length which would allow me to work 10m-40m.  It would also allow me to run ladder line only 20-30 feet before entering the shack or external balun and then about 10' of coax into the shack.  I could also get the wire about 30 feet off of the ground and it would be far easier to service than the dipole.

Given this, would this be a practical antenna?  Max power would be around 50w.

I use 65 feet of coax just to get to the dipole in my attic.   75 feet of coax on HF won't be a problem.

I've worked a lot of hams who are very pleased with their loops.

If it's a non-conductive roof, you could used electric fence insulators to stand off the wire.

75 feet is not far at all. And if you do build the loop put a balun or tuner right at the feedpoint since it is conveniently attached to the house and not hanging in the air.

Of course the correct arfcom answer is to build both
