My point of all of this is the form factor reduction really worth the complexity and performance hit?
That's a thought-provoking question! I haul around a lot of antennas, but the difference in size really doesn't make much of a difference for transport.
Until the UA860V appeared, my main VHF omni was a 1/4λ wideband ground plane with 3 foldable counterpoise elements that had around 2dB of gain. What sealed the deal for me was the third time that I had to repair it because of other departments' carelessness around such a large instrument. It's not fragile, but it can't stand up to moving trusses and set pieces crushing or scraping against it. The UA860V's size allows it to be placed in more out of the way places. Since VHF losses are so low in good cable, not much gain is often required.
