    What do people normally do when attaching a wire antenna to the exterior of a house?

    I'm wondering if I need some sort of insulator and if it's okay to have the wire touching the wall, i.e. will the wire detune if it touches a wet wall. It's going to be under a soffit, so it will be somewhat protected either way.

    Can i get away with those cheap white plastic things? 51aXnSkzcAL._SL1224_.jpg

    Use insulated wire.

    How well such an antenna installation actually "works" depends very heavily on the construction materials used for the house. Aluminum gutters are bad; plastic ones are fine. Stucco siding is bad; cedar (wood) shingles are fine. Aluminum siding (!) is terrible.

    Everything other than air, a vacuum or most gasses are variable RF dielectrics that can be "RF friendly" or very "RF unfriendly." Experience teaches us that stucco house siding, for example (which my house has, and probably 75% of all houses in southern CA have because it's a good heat insulator and pretty fire retardant), is absolutely terrible for RF and acts like a shield. "Wood" is fine, especially at HF.

    Try it and see!:)

    JASON,

    FIRST OF ALL ARE YOU THE OWNER OF THIS HOUSE, ARE YOU AUTHORIZED TO
    PUT FIXTURES ON THE BUILDING????

    ALSO, BE SURE TO STAY AWAY FROM POWER LINES.

    YOU MUST KEEP IN MIND THAT IN THE WINTER MONTHS
    YOU COULD HAVE AN ICE STORM AND THAT MAKES A SIMPLE
    WIRE VERY HEAVY.

    YOU MIGHT HAVE TO USE A BIG EYE BOLT AND THE APPROPRIATE
    INSULATORS TO PROPERLY RESTRAIN THE WIRE TO THE BUILDING.

    HAVE FUN AND WORK SAFELY.

    He said he's running it under the eaves of his house and attaching to the house.

    yes, I own the house. it's wood siding and metal gutters. I bought a MFJ 1984HP 40m EFHW. The wire is insulated.

    Go for it!

    But if you have HF gear "now," the ARRL 10 meter contest is this weekend, and you have both phone and CW (and digital) privileges on 10 meters. This only happens once a year, and right now is the time.
