The TBMA12 is a hybrid measurement antenna, which combines a conical and log periodic antenna to achieve a flat wideband frequency response for EMC pre-compliance testing. The antenna features a 30MHz to 6000MHz frequency range and 130W continuous input power. The TBMA12 has a <3:1 VSWR rating for frequencies over 75MHz. There is a 22mm mounting shaft present, which can be used to mount the antenna on one of Tekbox's tripods, such as the TBTP5 or TBTP6.
