An otherwise very good 70cm yagi has a boom and clamp plate with
pre-drilled quarter-inch holes: their _centers_ are 1 and 7/8 inches
apart. The correct u-bolt was missing.
Don't ask how how many places (including McMaster) and how long I've
looked for a u-bolt with centers of its [ends] 1 and 7/8 inches
apart. I've learned there are about a half-dozen common u-bolt
sizes, and for that dimension none come close.
Help will be appreciated. Bolt stock section 3/16 inch should be
good; 1/4 inch would be very tight.
