I needed an extension for my charging pile, as the RTK antenna was placed high up on the roof of the house. Luckily, ANTHBOT offered an extension, and at about $30, it seemed worthwhile. Shipping was relatively quick, and plugging the extension cable into the charging pile, and then into the RTK antenna was a breeze. I like that there is a screw cap that goes over the connections, to keep rain and such away from the metal connectors. The 30 feet was just long enough for my use, though a 50 foot one might serve other people well. I am a little concerned with the thickness/insulation of the cable...it is a little thin, in my opinion. I have it running over the roof of my house, and part of the wire is against the eave (which is kind of sharp, so I hope over time it doesn't wear on the wire and cut into it. I may have to put a soft buffer where the wire contacts the eave. Other than that minor quirk, the extension cable is well worth the money for the convenience of having the charging pile in a totally different spot than the RTK antenna. I highly recommend this product if you need to put the RTK antenna in a different spot than your charging pile!
