    A change of plans where I intended to route a coax from the noise antenna to the noise canceler unit puts it too close to cable TV internet both running both parallel and crossing it. The back porch the coax to be installed will run across has a cement floor with a 6 inch high cement ledge. I would like to run the cable along the ledge where it meets the floor "tacking" it every few feet with an adhesive just to hold it in place and well out the way of foot traffic. I really don't want to drill and install cement anchors for this project. Has anyone used an adhesive they can recommend? I'm concerned about possibility of an adhesive damaging the coax jacket.

    Thanks for reading. Have a great day.

    I would test a short length before the full glue-down but I suspect two-part epoxy would be dandy.

    I'd use some silicone sealant. It would last as long as you need it and still be easy to take out later. Would be safe for a p!astic coax jacket -- usually PVC I think.

    Hot glue often works surprisingly well and is removable, too. I prep large or long surfaces with a heat gun before applying.

    Adhesive silicone sealant will work. This is stronger than plain silicone caulk, they are not the same. Either would probably work.
    It can be removed, but will require using a stiff wire brush. You can not easily get it out of the concrete, you will end up removing the surface of the concrete where the sealant was, so the texture and color of the concrete will change too in those areas.

    Try Gorilla Glue. That stuff really works.

    I vote for hot glue. Easier to remove when the time comes.

    I'd put your chosen adhesive directly on a short piece of coax and wait several days for the adhesive to fully cure and set. Then see if the ahhesive had any effect of the jacket.
