Coax Run

I went to Home Depot and bought a small weather head as used on service entrances, short section of 2" PVC and 1 Fernco coupling.
Use a hole saw to bore the hole inside and out, cut the PVC to length, cut the Fernco coupling in half so that you now have 2 shorter sections.
Install one half of the Fernco on the inside end of the PVC and slide it through the hole to the outside, slip the other half of the Fernco onto the pipe and push it all the way up against the house.
now knock out the appropriate hole in the weather head, install your coax and assemble the weather head to the PVC.
Remember to put a drip loop in your coax.

The weather head displayed was for informational purposes.
I bent LMR-400 to go through mine using a tubing bender to form a long radius bend to minimize stress on the coax.
Same method used to form the drip loop. My Daddy would whoop you for putting a sharp bend in coax. :laugh:
No bends were acceptable with a radius any tighter than 10 times the diameter of the coax being bent.

Yep. The Navy used to specify, and maybe still does, a 13x diameter standard. 10x is fine for just about any coax type and application. Just make sure to keep RADIUS and DIAMETER clear in your mind.
Dia x 10 suited my cantankerous Engineer Father. Formula for Heliax was Dia x 15.
I would give a plugged, wooden nickle if he was still here today to drag out his tape measure and double check one of my bends to make sure it met his approval. :laugh:

If I did that here at my QTH, I would be frozen in the winter months with the cold and wind, then shot by the XYL. But then again I'm in a farm house that dates back to the 1900's and they used field stone for insulation.
leave some slack to move your gear around, maybe 5-10ft then after that make it as short as possible
If you can't go 'through', how about going over or going under? Got a window close to your radio? Put a board in that window and shut the window on that board to close it. That board only has to be a few inches 'tall', basically just enough to drill a hole in to allow the coax through. How about the opening at the top end of that window pane? Stuff a towel, or some foam in there to seal it. How about an eave vent? Or a 'crawl space' under the house?
Whatever works.
