I need a 3PDT RF relay rated for 15KW or better. Is the $38.95 Array Solutions relay the best, perhaps only, option? Thanks! David KD4E -- David (NOT Dave) Colburn, KD4E - Nevils, Georgia USA Safe &
Phil, AD5X, ID'd this as the same relay: http://www.galco.com/buy/Deltrol-Controls/21014-81 This is similar but lower power-handling capacity I think: http://www.westfloridacomponents.com/REL053APH06
This is to switch-in and out additional inductance at the base of a 43' vertical for 160 & 80m. It will occasionally be challenged with a 1KW+ (PEP) amp. I was directed here: http://www.galco.com/buy
