Why Outdoor Antennas Matter for ISP & WISP
Outdoor antennas are built to withstand the elements — heat, cold, moisture, dust, and even vibration. Unlike indoor antennas, outdoor units offer significantly higher gain, better directivity, and optimized radiation patterns for long-range links.
For ISPs and WISPs, performance, reliability, and ease of installation are paramount. Outdoor antennas must:
- Maintain a consistent signal over many kilometers
- Minimize interference in crowded RF environments
- Work well with sectorized and point-to-point systems
- Be rugged and weather resistant (IP65+)
Outdoor Antenna Types Explained
Parabolic Dish Antennas
Parabolic antennas use a reflector dish to focus energy into a tight beam. They are ideal for long-distance point-to-point (PTP) links, such as from tower to tower or between base stations.
Sector Panel Antennas
Sector antennas divide the coverage area into slices (sectors), perfect for wireless internet distribution to many subscribers around a central location.
Omni-Directional Antennas
Omni antennas radiate in a 360° pattern, providing wide coverage with moderate gain. They’re best for medium-range multi-client coverage.
Compact Dish & Point-to-Point Units
Smaller dish units, like the MikroTik LHG series, balance size with gain and are often used for shorter but still long links where space or budget is limited.
