Antenna Dipole SMA Plug 3300–3800 MHz 4dBi DA-072738-03-SMA

Product Description

Antenna, Dipole, SMA Plug, 700–960 / 1700–2700 / 3300–3800 MHz, 4 dBi, DA-072738-03-SM

Part Number: DA-072738-03-SM

The DA-072738-03-SM is a flat-type dipole antenna with an SMA plug (male), designed for 50 Ω wireless equipment. According to the OEM specification, it covers three key bands with the following nominal gains: 700–960 MHz 1 dBi, 1700–2700 MHz 4 dBi and 3300–3800 MHz 4 dBi. The antenna plane is oriented left–right relative to the SMA connector, making it a compact “stick” aerial that works well directly on the device housing.:contentReference[oaicite:0]{index=0}

This antenna is a simple screw-on upgrade wherever a standard SMA female antenna port is available, improving signal strength and reliability in tricky spots while remaining essentially omnidirectional in azimuth.

• Flat dipole antenna for SMA plug (male) interface
• Impedance: 50 Ω
• Frequency coverage (typical gain):
  • 700–960 MHz – 1 dBi
  • 1700–2700 MHz – 4 dBi
  • 3300–3800 MHz – 4 dBi
• Supports LTE / 4G bands, 5G bands around 3.3–3.8 GHz (n77/n78) and many IoT use-cases
• Dipole radiation pattern with broadly omnidirectional azimuth coverage
• Flat, compact form factor – antenna plane left/right from the SMA plug

Verified compatibility (examples)

This antenna is suitable for any 50 Ω device with SMA female antenna ports. It matches the connector type and frequency ranges recommended for many 4G/5G routers and dev kits:

• Teltonika 4G/5G routers and gateways (e.g. RUT240, RUT950, RUTX11, RUTX50, TRB500)
  Teltonika specify external antennas with SMA male connectors, 50 Ω impedance and LTE/5G bands including 700–960, 1700–2700 and 3300–4200 MHz, which this antenna meets.:contentReference[oaicite:1]{index=1}
• MikroTik Chateau LTE12 and similar LTE routers
  These routers provide SMA female connectors for external LTE antennas; the DA-072738-03-SM plugs straight on and covers typical LTE and 5G bands used with these devices.:contentReference[oaicite:2]{index=2}
• 5G evaluation / development boards with SMA antenna ports
  Many Quectel 4G/5G EVB kits and similar boards ship with or expect SMA-male external antennas across 600–6000 MHz; this antenna is suitable where the required bands fall within 700–960, 1700–2700 or 3300–3800 MHz.:contentReference[oaicite:3]{index=3}

Other equipment with SMA female cellular ports (for example industrial IoT gateways, serial/LTE modems and SDR front-ends) can also use this antenna, provided they are 50 Ω and operate within the supported frequency ranges.

Typical applications

• 4G / 5G routers, gateways and CPE with SMA antenna ports
• Private LTE / 5G and CBRS installations in the 3.3–3.8 GHz band
• IoT and telemetry devices needing a compact on-device antenna
• General RF lab / test work where a wideband SMA dipole is required

Compatibility notes
Fits equipment with a standard SMA jack (female) antenna connector and 50 Ω RF ports. Not suitable for RP-SMA, TS-9 or 75 Ω systems; adapters are required if those connector types are present.
