Technical Advantages

1. Wide 617–4200 MHz Frequency Coverage

The antenna provides broad frequency coverage from:

617 MHz to 4200 MHz

This allows multiple cellular frequency ranges to be supported by a single antenna design.

2. Multi-Band Cellular Compatibility

The antenna covers four specified frequency ranges:

617–806 MHz

806–960 MHz

1710–2700 MHz

3300–4200 MHz

This makes it suitable for multi-band RF coverage systems where several cellular bands need to be distributed through a common antenna infrastructure.

3. Directional Log Periodic Design

The log periodic antenna structure provides directional radiation characteristics across a wide frequency range.

This makes the antenna suitable for applications where RF energy needs to be concentrated toward a specific coverage area.

4. Specified Gain Across Multiple Frequency Bands

The antenna provides a specified gain of 7.5 ± 1 dBi in the 617–960 MHz range and 9 ± 1 dBi in the 1710–2700 MHz and 3300–4200 MHz ranges.

5. Low VSWR Across the Specified Bands

The specified VSWR is ≤1.8 at 617–960 MHz and ≤1.6 at 1710–4200 MHz.

6. Low-PIM Performance

The specified third-order PIM is:

−153 dBc @ 2 × 2 W

Low PIM performance is particularly valuable in multi-band cellular RF systems where passive intermodulation can affect receiver performance.

7. Compact and Lightweight Design

Dimensions:

440 × 210 × 65 mm

Weight:

0.54 kg

The compact and lightweight construction simplifies installation on poles, brackets and other RF mounting structures.

Working Principle

How Does a Log Periodic Antenna Work?

A log periodic antenna uses a series of radiating elements with different lengths and spacing to provide broadband directional RF performance.

The antenna receives RF signals from a connected wireless communication system and radiates them toward the intended coverage area.

In the transmit direction:

RF Equipment → Feeder Cable → Log Periodic Antenna → Coverage Area

In the receive direction:

Coverage Area → Log Periodic Antenna → Feeder Cable → RF Equipment

Because the antenna covers a wide frequency range, one antenna can support multiple cellular frequency bands within its specified operating range.

The antenna itself does not perform RF amplification or optical conversion; it functions as the RF radiating element at the end of the distribution system.

Applications in DAS and Repeater Systems

The LC-AR617-4200V09i60B-4310F can be integrated into various RF coverage architectures, including:

Base Station → Repeater / DAS → Feeder Cable → Log Periodic Antenna → Coverage Area

For fiber-optic distributed coverage:

BTS → MU → Optical Fiber → RU → RF Distribution → Antenna

The wide frequency range allows the antenna to support multiple cellular bands within the specified frequency coverage.
