Teradek Replacement Bolt 4K Horizontally Polarized Mushroom H Antenna

This is the mushroom-profile horizontally polarized antenna that ships on Bolt 4K systems, sold singly as a replacement. It is designed to work alongside the V antennas rather than replace them: two H and two V on the transmitter, matched by two of each on the receiver, gives the radio two perpendicular polarizations to work with and a genuinely independent second path to recover the signal from.

That pairing pays off most at medium range and in spaces that throw a lot of reflections back at the receiver, and it holds a measurable advantage over V antennas alone when shooting outdoors. Order one to replace a bent or lost antenna without rebuying a full set. This part is specific to Bolt 4K; Bolt 6 uses the current flexible H antenna instead.
