Description

Frequency: around 1575 MHz ± some MHz RF Connector House +2 TradeIndia +2 Polarization: Right‑Hand Circular Polarization (RHCP) usually, for GPS satellites. RF Connector House +1 VSWR: should be ≤ ~2.0 to avoid big losses. RF Connector House +2 antennix.rfconnector.in +2 Connector: commonly “N Female”, sometimes SMA, depending on cable. Outdoor versions often use more robust connectors. RF Connector House +2 TradeIndia +2 Cable: RG‑58 or similar. But with long length, signal‐loss matters a lot. High gain may compensate some. RF Connector House +2 TradeIndia +2 Power / Active vs Passive: Many 38 dBi antennas are “active” (they include an LNA) and need ~3‑5 V supply.

Use low‑loss cable and keep cable runs short if possible. Size and Directionality: Higher gain often comes with narrower beamwidth. If it’s directional, you’ll need to aim it more precisely. Omni high‑gain antennas are harder to make in practice. Power / LNA: Active antennas (with amplifier) need a clean power supply. Noise, voltage drop over cable, etc can affect performance. Weather & Mounting: Outdoor antennas should be weather sealed, resistant to UV, temperature extremes, water ingress. Mounting must be stable and ideally elevated with good sky view (less obstruction). Claim Verification: Many antennas list exaggerated gain. Request datasheet with radiation pattern and actual measurement if possible.
