Fig. 11: Recommended threaded socket mounting of VEGAPULS C 21 If the reflective properties of the medium are good, you can mount VEGAPULS C 21 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. Note: When mounting on longer sockets, we recommend carrying out a false signal suppression (see chapter "Parameter adjustment").
