The voltage at 500 watts would be 224 volts peak. In fact, 1500 watts would be 387 volts peak. Well within the 500 volt peak rating of the BNC and the 500 volt peak rating of the UHF connector according to Amphenol. The N connector is rated at 1500 volts peak, which is odd since the center of it is the same dimensions as the BNC connector. The output of the tuner is another matter as to a possible peak voltage... But I run all BNC connectors in my shack, have for decades and never had an issue with up to legal limit. I do have a UHF jack at the output of my tuner, connected to a UHF plug on a balun. By the way, UHF connectors are not 50 ohm connectors, but are non constant impedance connectors. 50 ohm BNCs are of course 50 ohms

The back panel (from left to right) has a heavy screw with wing nut for ground, four SO-239s (ANT3, ANT2, ANT1, XMTR), a 2.1 mm coaxial jack for 12V DC power, two RCA phono jacks for amplifier PTT key line interrupt (you would not normally use these for an Elecraft K3 / KPA500), a 3.5mm TRS jack labeled AH-4 that can be used with ICOM transceivers with a TUNE button and a four-pin Molex tune connector, a 3.5mm TRS jack labeled PC Data that uses a device like the KXUSB USB-to-serial adapter, or the same serial cable that is used for the W2 or XG3), and two 15-pin accessory connectors for connection from K3 to KAT500 to KPA500.
