For people that have these can you tell me if your blue light blinks. I have purchased two and was very careful not to powering them up until fully connected to the transmitter and antenna. Both when turned on just have a constant blue light no flickering as stated in the manual. The booster is a suntans 2000mW 5.8GHz. My distance I have been able to reach on a stage 4 kit has only been 3000 feet I was thinking maybe its the booster, or maybe only the 2.4 flickers.
