Elsema: Frequently Asked Questions
What is the benefit of using 915MHz for wireless control?
The 915MHz frequency band is widely used for industrial and commercial remote control because it provides a more robust and reliable link than the other frequency bands in environments with significant electronic noise. It also supports Frequency Hopping Spread Spectrum (FHSS), which reduces interference and prevents signal jamming.
What does Ground Independent mean for these antennas?
Most antennas in the Elsema 915MHz range, such as the ANT915S and ANT915M, are ground-plane independent. This means they do not require a metal surface (like a car roof or large metal cabinet) to act as a ground to function correctly. This makes them highly versatile for mounting on plastic enclosures, brick walls, or timber posts.
Which Elsema products are compatible with these antennas?
These antennas are specifically engineered for the Multicode (MCR series) receivers and any other devices operating within the 870MHz to 960MHz frequency range. They are ideal for expanding the range of long-distance RF control and telemetry systems.
What is the difference between the 915Mini and the ANT915M?
The 915Mini is a compact 20cm whip designed for portable applications or direct attachment to equipment. The ANT915M is a high gain, 65cm fibreglass collinear antenna designed for fixed installations where maximum range is the priority, offering a significantly higher gain of 6.5 dBi.
What is the maximum range I can expect?
When using a high-gain antenna like the ANT915M in a clear line-of-sight environment, the 915MHz Multicode system can achieve operating distances of up to 350–500 metres. The actual range will vary depending on the antenna height, local obstacles, and the sensitivity of the receiver.
Can I mount a 915MHz antenna inside a metal control cabinet?
No. Metal surfaces block radio signals at this frequency. For optimal performance, the antenna must be mounted outside the metal cabinet. You can use the included 3.6-metre coaxial cable to position the antenna on the exterior while the receiver remains protected inside the box.
What type of connectors are used?
Most models come with a high-quality SMA connector, which is the standard for 915MHz equipment. Some models, like the 915S-N, utilize an N-type connector at the base for a low-loss connection.
Does the length of the coaxial cable affect performance?
Yes. At higher frequencies like 915MHz, signal loss (attenuation) occurs within the cable. Elsema uses low-loss coaxial cable to minimize this. While 3.6 metres is the standard length, avoiding sharp kinks or loops will ensure the strongest possible signal reaches your receiver.
What is a Low Profile antenna (ANT900LP) used for?
The ANT900LP is a rugged, puck-style antenna that sits only 40mm high. It is designed for applications where a standard whip antenna might be at risk of vandalism or mechanical damage, such as on top of outdoor utility boxes or public access control panels.
Can I use a 915MHz antenna for 433MHz equipment?
No. Antennas are tuned to a specific frequency range. Using a 915MHz antenna with 433MHz equipment (or vice versa) will result in extremely poor range and could cause a high Standing Wave Ratio (SWR), which may damage the transmitter. Always match the antenna frequency to the frequency of your wireless device.
