HE-series antennas are designed for direct PCB mounting. Thanks to the HE's compact size they are ideal for internal concealment inside a product's housing.
The HE is also very low in cost, making it well suited to high-volume application. HE-series antennas have a very narrow bandwidth (approximately 10 MHz of the specified center frequency); thus, care in placement and layout is required. In addition, they are not as efficient as whip-style antennas, so they are generally better suited to use on the transmitter end where attenuation is often required anyway.
Use on both transmitter and receiver ends is recommended only in instances where a short range (>30% of whip style) is acceptable.
