Omni radiation from 30m to 15m, somewhat directional on 10m. For long-duration portable outings, or fixed station use (if you have the room), I'd go with the loop antenna simply due to the economics ($20 for wire vs. about $150 and up for a commercially made multi-band vertical) and because I'm partial to homebrew wire loop antennas. The cubical quad or quad loop is a square-shaped antenna. The formula "1005 / Freq (MHz)" is used to calculate the size of this inverted Delta Loop using either, a 4:1 balun for a multi-band antenna, or a 75ohm quarter wave section from the feed point to the 50 ohm feeder for mono-band operation."
