- Base Station Antennas Send and receive RF energy from the tower top. Match the antenna pattern to your coverage — omni for broad sites, Yagi for point-to-point, discone for wide-band. Browse 139 products
- Duplexers Share a single antenna between transmitter and receiver on adjacent frequencies. Required for any single-antenna repeater — keeps the TX from desensing the RX. Browse 102 products
- Cavity Filters Clean the RF path by passing wanted signals and rejecting unwanted ones. Bandpass clears the band; notch rejects a specific interferer. Browse 204 products
- Transmitter Combiners Combine multiple transmitters onto a single antenna. Lets a site run 2–16 channels through one feedline with controlled isolation and predictable insertion loss. Browse 31 products
- Receiver Preselectors Narrow the receiver's intake to just the band of interest. Reduces front-end overload from strong off-channel signals at busy sites. Browse 42 products
- RF Isolators Block reflected power from re-entering the transmitter. Protects the PA from antenna mismatches and prevents intermod from neighboring TXs. Browse 27 products
- Crossband Couplers Share one antenna across two different frequency bands. Common for sites combining a VHF and a UHF service on the same tower-top antenna. Browse 2 products
- IM Suppression Panels Pre-built isolator + filter assembly that suppresses transmitter intermod. Saves rack space and integration time versus wiring discrete parts. Browse 6 products
- Power Dividers Split one transmitter's signal across multiple antennas. Used for multi-sector coverage or driving an antenna array from a single radio. Browse 7 products
- Coaxial Loads Absorb RF energy without radiating it. Used as dummy loads for transmitter testing or to terminate unused ports. Browse 10 products
- RF Power Monitors Continuously read transmitter forward + reflected power. Used for unattended site monitoring and alarm-on-fault setups. Browse 8 products
- Tower-Top Preamplifiers Amplify weak receive signals at the antenna before feedline loss erodes them. Most useful when system noise figure is feedline-limited (long cable runs or low-loss-cable budgets). Browse 13 products
- Receiver Distribution Panels Split one antenna's receive signal across multiple receivers with active gain. Standard for hot-standby and multi-receiver shared-antenna setups. Browse 71 products
- TX / RX Filters Clean transmit harmonics and reject receive interference. Pair with isolators on the TX side, with preselectors on the RX side. Browse 6 products
- Wattmeters + Test Equipment Read accurate RF power and VSWR for installation, tuning, and field service. Bench-top and inline portable styles. Browse 9 products
- Receive Preamplifiers Rack-mount and inline receive preamplifiers — gain in the receive path. Tower-top units, which carry their own preselector and enclosure, are a separate type. Browse 3 products
