Hello, After a week of fixing equipment (still ongoing) I've finally been able to make some solid antenna measurements! It's still very much a work in progress and will likely take all of this week as well, but it's being documented on this brand new wiki page: https://www.hamwan.org/t/tiki-index.php?page=Antenna+Analysis&structure=HamW...

The ARC Wireless TX antenna: The frequency tripler (top) and amplifier (bottom): The 8660C sweeping signal source: The Laird RX antenna (bottom left) and the 8566A taking the measurement: The 2 specans that needed fixing (1 in progress still): The facial reconstructive surgery work for the top specan: Ever onward, --Bart
