BH7HQT When using a vehicle chassis as the ground, does the antenna need to consider grounding issues when using a vehicle chassis as a support or as a handheld radio? Or can installing a ground network optimize the VSWR under favorable conditions? Thank you!
BG2EFX BH7HQT The UV table doesn't need to be considered; at least a size of 70cm is sufficient, and you can consider a size of 2 meters if necessary. As for HF, it depends on the type of antenna. If it's a GP type of antenna, then it definitely requires a ground network.
BG2ELG What's needed is a GP antenna vehicle, which essentially constitutes the "ground network." Since we already have the vehicle platform, it should also be possible to set up the ground network. The more and longer the ground cables are, the better.
