Log-periodic, yagi, wideband and MIMO antenna designs

How does the outdoor antenna construction differ across the Carant range?

The log-periodic and yagi designs have different mechanical dimensions. The WLP, WLD, WLT-3G and WLQ-4G models measure 137 x 147 x 22 mm, weigh 114.8 g and use copper, ABS and FR4, with a specified wind resistance of 25 m/s. The AGY yagi models measure 347 x 132 x 75 mm, weigh 315 g and use aluminium, ABS and tin-plated brass, with a specified wind resistance of 45 m/s. The LPA versions use aluminium alloy, corrosion-resistant steel, ABS and polycarbonate, together with RG-223 cable and mounting for masts with a diameter of 30-60 mm.

How do antenna gain, VSWR and impedance differ?

Antenna gain and 50 Ohm impedance of Carant models

The listed models have an impedance of 50 Ohm. Depending on design and frequency band, the documented gain ranges from 4 dBi up to a maximum of 13 dBi. The WLP is specified with 6 dBi at 900 MHz, the WLD with 4 dBi at 900 MHz and 5 dBi at 1800 MHz, while the WLT-3G and WLQ-4G are specified with 4 dBi. The AGY yagi models have values of 10.5 and 11 dBi, while the LPA wideband models provide maximum values between 8.5 and 13 dBi depending on the frequency band. The specified VSWR limits vary between values below 1.5:1, 1.7:1, 2:1 and 2.2:1.

Polarization, radiation angle and directional antenna design

Which polarization and radiation angles are specified for Carant mobile communication antennas?

The products in the category are specified with vertical polarization. Radiation angle is not listed separately for every model: the AGY-10 is specified with a value below 45 degrees, while the LPA 427, LPA 727, LPA 827 and MIMO LPA 827 models are specified with 60 degrees. The technical data for the LPA 427, LPA 727 and LPA 827 specifies an F/B ratio above 15 dB, while the WLQ-4G technical data specifies an E/H ratio above 20 dB.

Which antenna connectors and mechanical characteristics are available?

Antenna connector, cable and mast mounting in the Carant range

The connector type varies according to the model design. The WLP and AGY yagi models are specified with an FME male connector, while the WLD, WLT-3G, WLQ-4G and LPA models listed in the webshop are specified with an SMA male connector. The technical data for the LPA 427, LPA 727 and LPA 827 also lists SMA female and male versions, while the LPA 827 installation material additionally identifies N male and female connector versions. The LPA models use RG-223 cable and can be mounted on masts with a diameter of 30-60 mm.

Pros - documented advantages and characteristics:

• The LPA 427, LPA 727 and LPA 827 are specified as wideband, high-gain directional antennas.
• The WLQ-4G is a quad-band indoor and outdoor antenna specified for GSM 900, GSM 1800, GSM 1900, UMTS, WLAN and LTE bands.
• Simultaneous use of GSM and 3G/4G frequencies is specified for the WLQ-4G.

Alongside the wideband and multiband designs, the exact frequency, power and connector specifications must be checked separately for each model.

Cons - documented differences and limitations:

• Maximum input power varies by model and is specified as 6 W, 10 W, 15 W or 25 W.
• Frequency range, gain, VSWR and connector type are not uniform across the entire category.
• Mechanical dimensions, weight, wind resistance, materials and mounting differ according to antenna design.

Because of these technical differences, the products in the category cannot be treated as antennas with identical electrical and mechanical specifications.

Summary of Carant GSM base station antennas

What role do mobile communication, impedance and antenna design play in the Carant GSM antenna category?

The Carant GSM base station antenna range includes several separate frequency bands, log-periodic and yagi constructions, wideband LPA models and the MIMO LPA 827 design. In addition to the common 50 Ohm impedance and vertical polarization, gain, VSWR, maximum input power, radiation angle and connector type vary between models.
