GEPRC Momoda2 5.8G DUAL Antenna RHCP SMA 170mm
GEPRC Momoda2 5.8G DUAL RHCP SMA 170mm Antenna – Stronger Signal, Fewer Dropouts
The GEPRC Momoda2 5.8G DUAL RHCP SMA 170mm antenna uses a dual-core RF solution to enhance gain and expand reception coverage. The manufacturer's own practical testing confirmed significantly improved directional compatibility. The antenna delivers stable, reliable image transmission in flight, with extended transmission range. This is the RHCP, SMA-connector, 170mm version — one antenna per pack.
GEPRC Momoda2 5.8G DUAL RHCP SMA 170mm Antenna Key Features
Dual-Core RF, +30% Gain
Two independent RF cores boost gain roughly 30% over a single-core design, for stronger signal and wider coverage.
Low VSWR at Band Center
A low voltage standing wave ratio keeps more transmitted power going into the air instead of reflecting back, for efficient transmission.
SMA Connector, Ultrasonic-Welded
A premium SMA interface with an ultrasonically welded housing for a tight, secure, long-lasting assembly.
Individually Spectrum-Tested
Every antenna is tested on a spectrum analyzer before it leaves the factory, to confirm it meets VSWR standards.
Dual-Core RF for Extended Range
The Momoda2 DUAL uses two independent RF cores instead of one, which the manufacturer's own field testing shows boosts gain by around 30% over a single-core antenna. The result is wider coverage, better directional compatibility, and a more stable video link at range.
GEPRC Momoda2 5.8G DUAL RHCP SMA 170mm Antenna Frequency Response
Centered at 5.65GHz across the 5.3–6GHz band, with return loss better than -11dB across the whole range. VSWR stays low through the middle of the band (around 1.1–1.2 from 5.5–5.6GHz) and rises toward the band edges, up to about 1.8 at 5.3GHz and 6GHz — measured performance is strongest in the core of the 5.8GHz FPV band, not just at the exact center frequency.
