Elsema: Frequently Asked Questions
Why should I use an external 433MHz antenna?
While many receivers come with a basic wire antenna, an external antenna significantly improves signal reception and transmission. It helps overcome obstacles like metal enclosures, walls, and environmental interference, ensuring a more stable and reliable wireless link for your PentaCODE® or Gigalink® systems.
Which Elsema products are compatible with these antennas?
These antennas are specifically designed for any device operating on the 433MHz frequency band. They are the ideal choice for enhancing the range of Penta series and Gigalink® series receivers, as well as transmitters that allow for external antenna connections.
What is the difference between the 433Micro and the 433Mini?
The 433Micro is a compact 45mm whip antenna with 0 dBi gain, designed for short-range applications where space is limited. The 433Mini is slightly larger at 18cm with a 1.0 dBi gain, offering a better balance between size and improved reception for general-purpose use.
How much range can I expect from the ANT433M high-gain antenna?
The ANT433M is a high-performance antenna with a 6.0 dBi gain and a 100cm whip. When used in an ideal line-of-sight setup with high-quality coaxial cable, it is designed to maximize the distance of your 433MHz system, potentially reaching the upper limits of the receiver’s rated range.
What is a Low Profile antenna (ANT433LP) used for?
The ANT433LP is a vandal-resistant, puck-style antenna that sits close to the mounting surface. It is ideal for environments where a standard whip antenna might be prone to accidental damage or tampering, such as on top of outdoor control cabinets or gate motors.
Do these antennas come with cables?
Models such as the ANT433S, ANT433M, and ANT433LP come standard with 3.6 metres of high-quality RG58 coaxial cable. The 433Micro and 433Mini are designed to screw directly onto the equipment’s SMA connector.
What type of connectors do these antennas use?
Most antennas in this range use a standard SMA male connection, which is compatible with the majority of Elsema receivers. However, the 433S-N model features an N-Type connector, which is often preferred for heavy-duty industrial installations.
Can I mount these antennas inside a metal box?
No. Radio frequency (RF) signals at 433MHz are shielded by metal. If your receiver is located inside a metal control box, you must mount the antenna on the outside of the enclosure and run the coaxial cable to the receiver to ensure the signal is not blocked.
Does the orientation of the antenna matter during installation?
Yes, for the best performance, 433MHz whip antennas should be mounted vertically.
Can I use these antennas with the Elsema 151MHz series?
No, antennas are frequency specific. These antennas are tuned specifically for the 433MHz band. Using a 433MHz antenna with a 151MHz system (or vice versa) will result in poor performance and could potentially damage the transmitter due to a high Standing Wave Ratio (SWR). Always match the antenna frequency to your equipment.
