    The 17’ telescoping whips that MFJ sells are what I have used in our travels the past
    few years.

    Your challenge is figuring out a mounting.

    Because I can not get them up more than 10-15 feet I almost always use them in an “L” form so it has a vertical-like radiation pattern. On 20 meters this gets out better than dipole that low. One hitch is that I have to add wire to lengthen them to tune around 14.2 MHz,

    I use that 17' telescoping whip also.... and it does work well for me. Instead of a wire to lengthen it, I use a coil. (see my post above). On 20m, I have a mark on the antenna, and open it up to just that spot. That set up make a a great travel antenna. It's not perfect for a permanent station, but it is really nice when sett up in a remote location.

    It sounds like a wolf river coils TIA would fit the bill nicely. It does have 3 radials, but the whole antenna can be set up and tuned in about 15 minutes. Tear down is about 5-7 minutes. I've made hundreds of contacts on mine and absolutely love it.

    Looks like a standard shortened vertical over a minimalist radial system (3 or so radials on the ground). With so few radials it probably matches coax quite well.

    I would try a ladder line fed doublet mounted vertically, center fed. No radials or RF ground required since it is a complete antenna. A mag loop also comes to mind.

    I have used a Tarheel ground mounted several times for a temporary antenna, works good with less than 20 radials. Used a TuneMatic Lite antenna controller. Fast and easy to setup and tune

    I have to declare I'm biased, but the Pro Antennas I-Pro Traveller sounds ideal for your application. Truly portable, low to the ground but still performs well. May be more than you are looking to pay though.

    Exactly what I use for portable operation - a 12- meter spider pole supporting a 7m vertical doublet. I guy halfway up, run the lower doublet leg along one guy and the ladder line down another. Works pretty well from ten to forty meters.
