Description
RadioMaster Dual Band 2.4GHz / SUB-G 900MHz T Antenna RP-SMA For Radiomaster Modules — BOLTON SKU 72807.
About the RadioMaster Dual Band 2.4GHz / SUB-G 900MHz
This radiomaster dual band 2 4ghz antenna is a T-style element that covers both the 2.4 GHz band and the sub-gigahertz 900 MHz band from a single radiator, terminated in an RP-SMA connector and stated by the manufacturer as compatible with RadioMaster modules. The radiation pattern is omnidirectional, so orientation relative to the far station is not critical. Peak gain is quoted as 3.83 dB at 2.4 GHz and 3.58 dB at 900 MHz, with a standing wave ratio of 1.27 at 2.4 GHz and 1.25 at 900 MHz, against a 50 ohm system impedance; those SWR figures indicate the element is matched on both bands rather than tuned for one and tolerated on the other. The coaxial tail measures 80 mm and total length is 100 mm, so the antenna can be routed away from the module body and positioned clear of obstructions. Quoted weight is 15.78 g and the item is supplied as two pieces.

Typical applications
Covering both 2.4 GHz and 900 MHz from one element means a single antenna can serve a control link that switches band, which reduces the number of fittings on a handset or ground module. The 80 mm coaxial tail is intended for installations where the radiating element must sit away from a metal chassis or a hand grip that would otherwise detune it. Supplied in pairs, the item suits diversity arrangements and spares holdings for module-based radio control equipment.
