Flat Panel Directional Antenna (Unwired), 3.4–3.7 GHz, 15 dBi – SuperPass SPPI15

Product Description

Flat Panel Directional Antenna (Unwired), 3.4–3.7 GHz, 15 dBi – SuperPass SPPI15

Part Number: SPPI15

The SPPI15 is a compact directional panel antenna for the 3.4–3.7 GHz band (often used for 3.5 GHz 5G / private LTE / CBRS-adjacent deployments). With ~15 dBi forward gain, it concentrates RF energy into a tight main lobe, improving SNR and range compared with small omnis or “rubber-duck” antennas.

This listing is the unwired variant: the panel’s RF feed point is provided without a fitted cable/connector so you can install the exact pigtail you need (e.g., N-female flylead, SMA-male, 2.92 mm, etc.). Keeping the jumper short and low-loss minimises feedline loss at 3.5 GHz.

• Frequency band: 3.4–3.7 GHz (3.5 GHz mid-band)
• Gain: approx. 15 dBi directional panel
• Impedance: 50 Ω
• Radiation: narrow forward beam with good front-to-back isolation
• Polarisation: linear (mount vertical or horizontal)
• Form factor: slim outdoor panel with rear mounting points for pole/wall brackets
• Unwired feed – fit your preferred short pigtail/connector

Typical applications

• 5G / private LTE links in the 3.5 GHz band (site-to-site or point-to-multipoint)
• Industrial wireless where a directional 3.4–3.7 GHz link is needed
• Noise-reduction scenarios where an omni picks up too much interference

Install tips

• Use a very short, low-loss pigtail from the panel feed to your radio; keep any longer run in thicker low-loss coax or locate the radio close to the panel.
• Mount high and clear; aim carefully – small pan/tilt changes at 3.5 GHz can make a big difference.
• Match polarisation at both ends (V-V or H-H) for best link budget.

Compatibility – quick check
Works with 50 Ω radios operating in 3.4–3.7 GHz. Because this is unwired, select the pigtail/connector that matches your device (e.g., N, SMA, TNC, 2.92 mm). Weather-seal all outdoor joints with self-amalgamating tape.
