A poorly optimized feeder system can waste up to 30% of transmitted power due to mismatches and losses. Start by keeping VSWR below 1.5:1—every 0.1 increase adds 1-2% loss. Use low-loss cables (e.g., LDF4-50A) over standard RG-213 to cut attenuation by 50% at 2GHz. Proper connector torque (e.g., 25 in-lb for N-type) prevents moisture ingress, […]

Passive antennas, which rely solely on external signal strength, typically deliver gains between 2 dBi and 10 dBi, making them ideal for short-range, low-interference environments. Active antennas, on the other hand, integrate built-in amplifiers (LNAs) to boost weak signals, offering gains up to 30 dBi or higher—critical for long-range or high-noise scenarios like satellite comms
