The Larsen CDL-34 NLA (Nulling Loop Antenna) is a high-performance circularly polarized receiving antenna designed for use in the L-band frequency range (1.2-1.45 GHz). This antenna is primarily used for precise tracking and measurement applications, such as in satellite communications, radio astronomy, andmeteorology.
The CDL-34 NLA employs a unique design based on a nulling loop concept, which enables it to produce significant reduction in unwanted noise and interference. The antenna features a compact, parabolic reflector shaped as an offset Gregorian configuration. The reflector is wrapped with an Erib Wideband Mono-Film feed with a rotation range of 360 degrees. This feed system allows the antenna to track and maintain a stable lock on satellites, while minimizing the need for manual adjustment.
The antenna radome is constructed from lightweight and durable fiberglass reinforced composite materials, providing excellent protection against environmental elements. It measures 117 cm (46 inches) in diameter and 134 cm (52 inches) tall. The gain of the antenna is approximately 12 dBi and the half-power beamwidth is around 2.5 degrees. The antenna includes a sealed closed-loop motor control box, offering external control through DC voltage inputs.
This robust and lightweight antenna can be easily mounted on a tripod or mast and comes with all necessary mounting hardware. The Larsen CDL-34 NLA is an excellent choice for satellite communication systems and scientific research applications requiring high sensitivity, low noise, and superior performance in tracking and measurement applications.
The Larsen CD antenna, specifically the Larsen ANLA-34 model, is a popular choice among mariners and aviation enthusiasts due to its rotary design and omni-directional coverage. Here are some pros and cons of buying this antenna:
Pros:1. Omni-directional coverage: This antenna covers 360 degrees, making it a great choice for receiving signals from all directions.
2. Rotatable: The ANLA-34 antenna can be rotated to optimize signal strength and direction, ensuring reliable communication.
3. Optional AIS receiver: This antenna can be used with an Automatic Identification System (AIS) receiver, allowing users to track other vessels and receive navigation information.
4. Durable construction: The ANLA-34 is made of high-quality materials and is resistant to corrosion, making it suitable for use in harsh marine environments.
5. Wide frequency range: This antenna can receive signals on VHF frequencies from 156 MHz to 162 MHz.
Cons:1. Cost: The ANLA-34 is a premium antenna and can be more expensive compared to other VHF antennas.
2. Size: This antenna is relatively large and may require additional mounting space.
3. Manual tuning: While the antenna does not require regular tuning, manual adjustments may be required to optimize signal strength and direction.
4. Potential for interference: The omni-directional design of the antenna makes it susceptible to interference from other signals, which can degrade performance.
5. Installation complexity: Installing and setting up the ANLA-34 antenna can be more complex than other antennas due to its rotary design and optional AIS receiver.
Conclusion:The Larsen ANLA-34 antenna is a high-performing, durable, and versatile choice for mariners and aviation enthusiasts who require reliable communication and navigation signals. Its omni-directional coverage and rotatability make it a great choice for situations where signal strength and direction can vary. However, its cost, size, and potential for interference may be drawbacks for some users. Ultimately, the decision to purchase the ANLA-34 should be based on individual needs, budget, and specific application requirements.
Recommendation:If you require reliable communication and navigation signals in a marine or aviation environment and have the budget for a high-performing antenna, the Larsen ANLA-34 is a great choice. Its omni-directional coverage and rotatability make it a versatile option for optimizing signal performance in various conditions. However, if you have limited budget or prefer a more straightforward antenna with a smaller footprint, there are other VHF antenna options available that may better suit your needs.
Checked for continuity using a multi meter. Comes as shown. Global shipping is usually available, but let me know if you don't see an option. My name is Hayden.
Appears to work fine. I will always answer them honestly.
