    I've had to manually take time to approve posts again due to use of @s

    Vbulletin does NOT use @s to tag like Twitter and other software platforms.

    New users using it are considered spamming an email. I again implore people to use quote function and not @.

    After not much improvement after changing from the dvbt clipped antenna to a home made spider antenna, I found a massive improvement in performance (a 30% boost) after moving the spider antenna just half a meter higher (a couple of feet).

    (1) For any antenna, increase in height makes a big difference if there are surrounding tall objects like buildings or trees.

    (2) For DVB-T stock whip, the magnetic base provides a very small and insufficient ground plane. You have to place it over a metallic plate such as cookie can or a food can to provide it a good ground plane. You will notice substantial improvement when you add a ground plane. The downward radial wires of Spider provide a good ground plane, and it does not need a can or metallic plate.

    Thanks. I had always wandered what the downward radial wires where actually for.
