the antenna - 4el-50Ohm-Yagi by DK7ZB, PVC pipe boom and alu tube elements;
since I don’t have a crimper, will probably abandon the BNC-BNC part and mount RG-58 -> SMA directly to rediator element. (I struggled with making a good connection on the boom for the BNC, wanted to make it cool but without a crimper it sucks)
