Do you want to place a medium to large mobile antenna on a metal part of your vehicle without mounting a permanent antenna base? The Sigma triple magnetic base offers a practical solution for this. This sturdy antenna base consists of three magnets, each with a diameter of 160 mm, and is designed for medium to large mobile antennas.
The central antenna connection is an SO-239 / UHF-female type. This allows you to mount a suitable mobile antenna with a matching PL connection directly onto the magnetic base.
For the connection to, for example, your mobile CB transceiver, 4.75 meters of coaxial cable with a PL-259 / UHF-male connector is included. This gives you the most important components for a magnetic antenna mount on your vehicle all at once.
Why choose a triple magnetic base?
A larger mobile antenna requires a suitable base. This magnetic base with three magnets distributes the mounting over three separate magnetic feet.
Each magnet has a diameter of no less than 16 cm. Together, the three magnets form a wide base for the antenna. According to the product specifications, this Sigma magnetic base is specifically designed for medium to large mobile antennas.
This makes it interesting when a single compact magnetic base does not match the size of the antenna you want to use.
The Sigma magnetic base is intended for mounting on a suitable metal surface of a vehicle. Think, for example, of the metal roof or a suitable metal trunk lid.
Because the attachment is magnetic, you do not need to make a permanent mounting hole for a fixed antenna base.
This makes the solution practical when you want to be able to remove the antenna installation or when permanent mounting on the vehicle is not desired.
The surface must of course be suitable for magnetic attachment. Therefore, check before mounting whether the desired position is actually made of suitable metal.
Protection between the magnets and the car paint
With a magnetic antenna base, you not only want a sturdy placement, but also take the surface on which the base is placed into account.
Where can you place the Sigma magnetic base?
The three magnetic feet are therefore provided with rubber protection. According to the supplied product information, rubber protectors are included to use between the magnetic attachment and the metal surface.
This helps to limit direct contact between the magnetic base and the paint, thereby reducing the chance of damage during normal use.
When placing, always ensure that both the underside of the magnetic base and the surface of the vehicle are clean.
Which antenna connection does this magnetic base have?
The central connection of this magnetic base with PL-connection is an SO-239, also called UHF-female.
A suitable antenna with the matching connection can be mounted on this.
On the other side of the installation, the supplied coaxial cable is connected to the transceiver. This cable has a length of 475 cm and is equipped with a PL-259 / UHF-male connector.
This makes the magnetic base suitable, for example, as a base for a matching mobile CB antenna installation.
For which antennas is the Sigma triple magnetic base intended?
According to the product specifications, this triple magnetic base has been developed for medium to large mobile antennas.
The three magnetic feet together form the base of the antenna installation. This is particularly interesting when you want to mount a larger mobile antenna magnetically and are looking for a triple version for that purpose.
The final suitability remains dependent on the antenna used, the mounting position, and the conditions in which the installation is used.
Main advantages
- Triple magnetic base with three separate magnets, each 160 mm in diameter
- Designed for medium to large mobile antennas
- SO-239 / UHF-female antenna connection for a suitable PL antenna
- Includes 4.75 meters of coaxial cable with PL-259 / UHF-male connector
- Three magnetic feet with rubber protection for the contact surface
Practical magnetic antenna mounting for your vehicle
With this Sigma triple magnetic base, you create a wide magnetic base for a suitable mobile antenna. The three magnets of 160 mm each make this model clearly different from a standard single magnetic base.
In addition, you immediately receive 4.75 meters of coaxial cable and a PL-259 connector for the connection to suitable radio equipment. The SO-239 connection on the base makes it possible to mount a matching mobile antenna.
Especially when you do not want to mount a permanent antenna base in the vehicle, a magnetic base with three magnets offers a practical solution. You can place the antenna installation on a suitable metal surface and remove it again if necessary.
Order the Sigma magnetic base with PL-connection from Deltron and give your medium or large mobile antenna a sturdy triple magnetic base.
