    The Elecraft T1 is a nifty autotuner.

    There are a number of QRP tuners that use a LED.

    If you can see it in bright sunlight in your pocket or in your waistpack worn in front with your transceiver or on the backpack shoulder strap pocket, for example, it is about as automatic as it gets.

    I like this one, on the antenna wire after the counterpoise.

    Not so. The ZM-2 uses coax to the rig (as does the T1), but it has both coax out and banana/ binding posts along with a "GND/LINK" switch setting.

    I have both a ZM-2 and T1. I like them both! T1 is smaller, but ZM-2 doesn't require a battery. T1 is fast and simple; ZM-2 is a bit fiddly as you need to tweedle both knobs simultaneously and the SWR nulls are VERY sharp. If fast/simple was my main concern I'd go with the T1; if ultimate reliability is a bigger factor, ZM-2 would be my choice as it's unpowered and has simple discrete components.

    I have used my ZM-2 to setup a loop in the park feeding it with ladder line. with a short run of coax from the tuner to the radio.

    don't forget to drag a counterpoise.
    if you're going to change bands on the move, make a multi-tail counterpoise.

    then there's http://www.alexloop.com/index.html

    it clips onto the co-ax. available from dxengineering: https://www.dxengineering.com/search?keyword=alextune&SortBy=BestKeywordMatch&SortOrder=Ascending

    Hello, I have a ham radio go bag which houses several different radios but i have a elecraft atu 1 and it works great. THis is the video I took before upgrading my kit with the auto tuner. hopefully it gives you some ideas. Instead of mounting the radio on my back its off to the side and I can carry it while hiking or camping with a regular backpack full food and water survival gear etc.. I remember when i was looking for a portable setup I was thinking about where I was going to put my other essential items. This is the only thing I could come up with was placing my radio in a sling bag like the vanquest mobius 2.0 Now You can shave weight off the bag and just carry the hf rig ( yaesu 817, Battery, Solar panel, Atu, mic, and antenna) instead of all the other stuff I carry in it. I wanted a modular system i could carry with or without a backpack. I wish you luck on deciding on an atu.
