Our GRAM™ Model HFG20* antenna, is a 6 meter, 2.1 section variation of the Model HFG30; also requires no formal foundation and is even easier to install and maintain in remote areas.
Our line of GRAM™ antennas are designed to be extremely environmentally friendly. Therefore, installation (and removal) impacts are minimal. Also, maintenance is generally limited to annual inspection and guy tightening, further reducing environmental impacts.
