Mast Adapter AA 9213 for antennas with 3/8 inch thread
Some antennas are equipped with 3/8″ female threads. This thread is also called the large camera thread. Such antennas can be directly mounted on tripods with 3/8 inch male thread, e.g. AM 9144. Adapters are usually not required.
Some mast systems use the widely used 22 mm antenna tube with indexing ring to fix the antenna. If the antenna is not equipped with a 22 mm tube the AA 9213 is required.
AA 9213 is perfectly suited for small antennas. Larger antennas might cause torque around the 22 mm tube. Such large antennas should only be mounted if the center of gravity is below the 22 mm tube.
The indexing ring can be shifted along the tube after loosening 4 grub screws. It can also be removed completely. The star handle screw 3/8″ is undetachably fixed to the adapter.
Applicability of Schwarzbeck AA 9213 Adapter with Various Antenna Types
| Antenna type | Applicability |
|---|---|
| BBHA 9170 | AA 9213 is perfectly suited. There is no height offset when rotated around the tube. |
| HFRA 5148 HFRA 5152 HFRA 5153 HFRA 5154 HFRA 5155 HFRA 5156 HFRA 5157 HFRA 5158 HFRA 5159 HFRA 5170 HFRAE 5160 HFRAE 5161 HFRAE 5162 HFRAE 5163 FESP 5133-7/41 | AA 9213 works well because possible torque is negligible. As the H-field pattern of these antennas is rotation-symmetric turning the antenna around the tube is usually not required. |
| FESP 5134-40 | AA 9213 works well but an additional thread reducing adapter TA 9204 is required. |
| HFRA 5149 HFRA 5150 HFRA 5151 FMZB 1513 | AA 9213 can be used. However these antennas are heavier and can cause torque around the 22 mm tube. They should only be mounted with the center of gravity under the 22 mm tube. |
