This is just another way to hookup that Broadlink IR transmitter to a pole light that usually are sold on IKEA stores, the pole diameter is about 15.7 mm, so u can adjust at your wish.
No need supports cause its printed flat down , i didn't move the clamp perpendicular cause the Broadlink design was made to place it on a table and all IR leds are placed all around the top, to reach at 360° surround it every IR peripherals ,so no need to put it at 90° like somebody did .
