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.
