FAQs

Frequently Asked Questions

What type of antenna is the AD-11/G?

Omnidirectional antennas are common in tactical communications systems, with dipoles often used for fixed site and portable applications. (src-af02a1f4d46a9891) The reviewed product data identifies the AD-11/G as a wideband dipole antenna, designed to be omnidirectional.

What platforms is the AD-11/G suitable for?

Omnidirectional antennas are typically optimized for platforms such as handheld, manpack, vehicle, tactical portable, or fixed site applications. (src-af02a1f4d46a9891, src-75fee6bf4644d22b) The reviewed product data states the AD-11/G is intended for stationary and portable use and is suitable for Fixed Site, Manpack, and Ground Vehicle platforms.

What frequency range does the AD-11/G cover?

Choosing an antenna that works for all expected frequencies is paramount for effective communication. (src-af02a1f4d46a9891, src-75fee6bf4644d22b) The reviewed product data lists the AD-11/G's frequency range as 136 to 176 MHz.

What is the maximum power the AD-11/G can handle?

Most tactical communications antennas are designed for moderate power levels. Selecting an antenna that matches the maximum continuous power output of the transmitter is crucial for the antenna's longevity. (src-af02a1f4d46a9891, src-75fee6bf4644d22b) The reviewed product data specifies a maximum continuous wave (CW) power handling of 400 W for the AD-11/G.

What gain can be expected from an omnidirectional antenna like the AD-11/G?

Omnidirectional antennas of standard dimensions typically offer gains between 0 and 2 dBi. (src-75fee6bf4644d22b, src-af02a1f4d46a9891) The reviewed product data indicates a gain of 0 to 1 dBi for the AD-11/G.

How does the AD-11/G's radiation pattern behave?

The radiation pattern illustrates how an antenna distributes energy into space. For vertically polarized, dipole-like antennas, gain is typically maximized perpendicular to the antenna, towards the horizon, with nulls towards the zenith and nadir. (src-639ec09cb3460302) An omnidirectional antenna generally aims for a circular pattern in the azimuth plane. (src-6bc089f174baf1c2) The reviewed product data confirms the AD-11/G's polarization as Vertical.

What are the mounting requirements for the AD-11/G?

Antenna form factor, including size, weight, and mounting details, significantly influences its suitability for a given application. (src-639ec09cb3460302) The reviewed product data states that the AD-11/G can be mounted on any metal tube with an inner diameter greater than 30 mm and an outer diameter less than 43 mm (e.g., a standard 1 1/4” tube). It also supports mounting using TRIVAL ANTENE's standard mounting console and adapter elements ADK.

What kind of connector does the AD-11/G use, and what is its impedance?

Choosing an antenna with a sufficiently well-matched impedance is important to minimize reflected power, which could otherwise damage a transmitter. (src-af02a1f4d46a9891, src-75fee6bf4644d22b) The reviewed product data specifies an N-type connector and an impedance of 50 ohm for the AD-11/G.
