FAQs

What type of antenna is the AD-10/E?

The reviewed product data identifies the AD-10/E as a wideband UHF/SHF dipole antenna, categorized as an omni antenna, supporting vertical polarization.

What is an omnidirectional antenna?

For omnidirectional antennas in general, they are designed to radiate and receive signals equally in all horizontal directions. This makes them suitable for applications where coverage across a 360-degree azimuth is required, without needing to reorient the antenna. For the current product, it is specified as an Omni Antenna.

What factors should be considered when selecting an omnidirectional antenna?

When selecting an omnidirectional antenna, consider the required frequency of operation, the maximum continuous power the transmitter will output, and the maximum VSWR the transmitter can tolerate. The platform to which the antenna will mount is also important; for fixed-site and portable applications, dipoles are often considered. Additionally, the desired gain and radiation characteristics, and the antenna's form factor (size, weight, and mounting details) are key. For the current product, the reviewed product data lists a frequency range of 400-6000 MHz, specific power handling, VSWR less than 2.5, and a fixed-site platform. The form factor includes dimensions of 590 mm height, 78 mm diameter, and 3.1 kg weight, with mast mounting up to 60 mm diameter.

How does antenna gain affect performance?

For omnidirectional antennas, higher gain typically means the radiated power is more focused, usually resulting in a narrower beamwidth in the elevation plane. It's important to note that higher gain doesn't increase the total power radiated by the antenna but rather concentrates it in specific directions. Omnidirectional gains typically range from 0 to 2 dBi for standard dimensions, though wideband omnis can have lower gain at the low end of their frequency range. For the current product, the reviewed product data lists a gain ranging from -2 to +4 dBi.
