Pending delivery of the kickstarter gateway, I have been busy with preparations to place a mast and antenna on my roof. The mast is of type Alumast EA4XL this is a telescopic mast with a maximum height of 5 meters. The antenna is a Taoglas OMB.868.B08F21. The result is an antenna at a height of 5 meters above the ridge of the roof, which is about 20 meters above ground level. After installing the gateway, I will publish the results on this forum.
