For medical telemetry! It has characteristics that make it less susceptible to interference even when approaching surrounding building materials.
The "CA-4251" is a 400MHz band wideband antenna for medical telemetry. It can be easily installed using two methods: on the deck plate behind the first floor or with ceiling-mounted bolts in the attic. Compared to standard whip antennas, it has a wider frequency range of 420 to 450MHz with lower standing waves, making it less susceptible to noise even if there are noise sources along the coaxial cable, and it is also less affected by nearby building materials. 【Features】 ■ The core wire and shield of the antenna connector are insulated. ■ The circuit will not short even when power for the receiving booster is added. ■ It is painted white. ■ The installation location of the antenna can be easily identified even in dark places in the attic. ■ It has lower standing waves over a wide frequency range of 420 to 450MHz compared to standard whip antennas. ■ It is less likely to pick up noise even if there are noise sources along the coaxial cable. *For more details, please refer to the PDF document or feel free to contact us.
