VHF antena za brodove smanjene visine

The MA 2-1SC-SHT antenna has a height of approximately 550 mm (55 cm). Its compact size makes it ideal for installations where space is limited.

Yes, this antenna is compatible with the vast majority of fixed VHF radios on the market. It supports a maximum power of 50 W and has a standard impedance of 50 Ω.

The MA 2-1SC-SHT antenna can be mounted in several ways depending on your installation. The technical documentation mentions mounting by:

ScrewsRivetsTie wraps (clamp straps)Mounting hardware (screws, rivets, etc.) is not included.

The antenna weighs approximately 0.4 kg, making it a lightweight and easy-to-install solution.

The antenna is fitted with a standard female UHF connector (UHF(f)). You will need a coaxial cable equipped with a male UHF connector (often called PL-259) to connect it to your VHF radio.

Thanks to its reduced height, the MA 2-1SC-SHT antenna is particularly suited for:

Sailboats
Powerboats
Any craft where a tall antenna would be cumbersome or exposed
Serving as a reliable and compact backup VHF antenna

The antenna is designed for maximum durability in marine environments. The main materials are:

Whip: Fiberglass with copper wire, covered in polyethylene.Base housing: High-gloss chrome-plated brass.

No, this is not an issue but a design choice. A gain of -3 dBd is the direct result of the antenna's very compact size. This is a technical trade-off to achieve a much shorter antenna than a standard model, which is a major advantage on certain boats. It provides reliable communication performance for standard-range use.

Yes, absolutely. The antenna's frequency range (156 - 162 MHz) fully covers the frequencies used by AIS systems (161.975 MHz and 162.025 MHz), making it perfectly compatible.

This antenna is designed to operate on the marine VHF band, with a frequency range from 156 to 162 MHz.

No, the antenna is supplied alone. The mounting bracket must be selected separately based on where you intend to install it on your boat (mast, pushpit, etc.).

The MA 2-1SC-SHT antenna can handle a maximum input power of 50 Watts, which exceeds the transmit power of most marine VHF radios (typically 25 Watts).

Yes, this is an omnidirectional antenna. This means it transmits and receives signals equally in all directions on a horizontal plane (360°).

This antenna is manufactured in Denmark by AMPHENOL PROCOM, a brand recognized for the quality of its professional communication equipment.

The antenna is designed to withstand extreme weather conditions and can operate within a temperature range from -30 °C to +70 °C.

Avoid installing the antenna parallel to metal parts such as masts. Although it is independent of the ground plane, proximity to metal will negatively affect SWR and the radiation pattern.

The MA 2-1SC-SHT antenna has vertical polarization, which is the standard for marine VHF communications to ensure optimal communication between vessels and coastal stations.

This antenna is robust and designed to withstand a wind load of 10.4 N, which corresponds to winds up to 160 km/h.

The nominal impedance of this antenna is 50 Ω (Ohms). This is the standard impedance for marine VHF radio equipment, ensuring perfect compatibility and optimal power transfer.

This refers to the antenna design type:

½ λ (half-wave): This is a very efficient antenna design.
Reduced: Indicates the antenna has been physically shortened compared to a standard half-wave to achieve its compact size.
End-fed: Means the coaxial cable connects at the base of the antenna, simplifying installation.
