The AM-741R is designed for radiated emissions testing below 30 MHz and includes:

Telescoping rod: Adjustable from 23 cm to 105 cm (approx. 41 inches for compliance with most standards)
Low-noise preamplifier: Enhances signal sensitivity and SNR
Power Indicators: RF ON/OFF, battery low, amplifier saturation, and charging status
Mounting: 1/4"-20 threaded hole for tripod mounting (compatible with Com-Power AT-220)

Applications

Compliance with standards such as:

Grounding & Installation

Standard Grounding: Counterpoise must be bonded to the ground plane where the EUT is installed
MIL-STD 461 Grounding:
- Output cable shield must be grounded via metallic bracket
- Ferrite (20–30Ω @ 20 MHz) must be centered between bracket and antenna
- Optional AMS-741 Grounding Kit available, includes:
  - Ferrite-fitted cable
  - Grounding bracket
  - Elbow adapter
