Draytek ANT-1205 | Omni-Directional Dual-Band Network Antenna
The Draytek ANT-1205 network antenna Omni-directional antenna RP-SMA 5 dBi is designed to enhance wireless performance for UK networks. This antenna kit is for users of DrayTek Vigor routers who need better signal distribution. It offers a dual-band solution for both 2.4 GHz and 5 GHz frequencies. Because it is omni-directional, it radiates signal equally in all directions. This makes it ideal for general coverage in homes or offices.
Slim Technical Overview
Here are the key specifications for the Draytek ANT-1205.
| Metric | Spec. |
|---|---|
| Antenna Type | Omni-directional |
| Connector | RP-SMA |
| Frequency Band | 2.4 – 5 GHz |
| Max Gain | 5 dBi |
| Pack Size | 2 pc(s) |
| Colour | Black |
Dual-Band Frequency Support
This antenna operates across both 2.4 GHz and 5 GHz bands. It supports IEEE 802.11a/b/g/n/ac/ax standards. The 2.4 GHz band offers a wider reach. The 5 GHz band provides faster data rates with less interference. Because it covers both, it is versatile for modern Wi-Fi demands.
Omni-Directional Coverage Pattern
The antenna features a 360° horizontal beam width. This provides consistent signal spread around the unit. It is suitable for central router placement in a room. However, it does not focus energy in one specific direction. So, it is ideal for general coverage rather than long-range point-to-point links.
Gain and Signal Efficiency
The maximum gain level is 5 dBi. Specific gains are 2 dBi at 2.4 GHz and 4.5 dBi at 5 GHz. Higher gain helps improve signal strength at longer ranges. It can also boost connection stability in borderline areas. This makes it a solid upgrade over standard low-gain stock antennas.
Physical Build and Durability
The antennas stand 198 mm tall with a 1.3 cm diameter. They are finished in black to match most networking hardware. The construction supports a power handling of 1 W. This ensures reliable operation under standard router transmission loads. Linear polarization is used for signal transmission.
