Arrived quickly.
This antenna is perfect for portable QRP use. The toroid core transformer is well wounded and solded. I just had to fix the core with an new cable tie. Also the the antenna and ground screws had to be tighten. But this was not an issue. The provided cables are of two different length. So you should connect the longer (in my case red) cable to the antenna terminal und the shorter blue cable to the ground terminal. Your transceiver need an antenna tuner to use this antenna für multiband operation.
