    The push-up pole has eyelets to attach guy wire. I have three short guy wires attached around three large tree trunks of the tree about twenty feet up in the tree. Nothing fancy but it's solid and been up about 20 years. I had bought the push-up pole from radio shack. It's similar to this one, telescoping.

    I’ve circled the block re half-wave verticals for the roof my all-aluminum trailer, and — as I’m away from home more days than not — I’m back to the quarter-wave whip, as:

    1). An A99 (or similar) isn’t going to do well laid over just above a roof baking at 160F most summer days.
    2). The expense of an alternative which might (better) survive is $600+
    3). It’s a mobile installation is what to keep in mind.
    4). Interference with neighbors is a potential to avoid (RV Parks frown on radio antennas).

    5). As it’s a mobile install, being able to use it near-immediately anywhere is its own priority.

    Will be worth testing with cooperative neighbor or two given a 102” permanent-mount. Got a NYE-VIKING to try.

    I am now thinking while typing, which may be dangerous. 108 inch whips in phase down the long axis of the travel trailer.

    I’m willing to listen anyone’s got this subject in hand.

    Just put up the vertical and paint it some natural color so its not that loud white color. Rattle can that sucker. I would choise the dipole hands down but if you cant get it up in the air it will be a dismal performer

    A dipole will be easy to hide and get it up in a tall tree or a tall object. Or like some have said a 1/4 wave in the center of the roof or even a short pole from the back bumper.

    “Metal roof” is why I responded to this thread. To wake up commenters. Mines a mobile install, but used while stationary. 102” SS whip with a layover appears best. I appreciate the posts earlier linked (replied) in helping this decision.

    I don’t believe a Fiberglas antenna will live long enough while laid almost against a super-hot metal roof in my case.

    I’d rather enjoy half-wave performance, but RFI & Neighbor problems ALSO preclude the A99 choice (and it’d need to be non-metallic paint).

    I have a couple of dipoles plus a bazooka to throw out if I park at a location I can use them. I agree it’s the way to go for stationary use & ease (easily hidden).

    The OP wondered A99 versus Dipole. In his case, why not both (parked long -term)?
