Currently, I have a XieGu G1036C, a 20-meter end-fed antenna, a full-size inverted V antenna covering two bands (14 MHz and 21 MHz), a 14.8V 12Ah battery pack. It seems that I need to modify it to have a direct output line in order to connect to high-power devices.
I'm looking to purchase a 50W PA (public address) system.
What's the difference between 50W and 100W? What does a 3dB change represent?
