I've seen several antennas made with portable clothesline reels and wire. I think I'd like that better as far as pliability and better connection. There are several portable 2M and 440 tape measure antennas online. Most are handheld satellite-style antennas. I would like to make one for SO-50 since it's a 2M uplink. I have an ELK log periodic, but it has to be taken apart and put back together. I always worry about bending an element, even though they're pretty tough. If I had something like the tape measure yagi, I would likely keep it in my work truck and try for SO-50 passes more often.
