Diamond X300 2m/70cm Colinear Antenna. Showing constituent parts, build and installation. Note: There is a weep/drain hole at the base of the antenna where you connect your coax plug. If you seal the male plug/coax with tape like I have done, make sure you don't accidentally block this hole which is next to the female connection on the antenna base. I haven't, and my installation has been fine for years now. This is one of many amateur/ham radio themed videos on this channel. Feel free to browse ๐, like ๐๐ป and subscribe ๐ 73 Ian.
