Increase CapacityDiplexers expand antenna capacity by allowing 5 GHz and 6 GHz links to operate through the same large, high-gain antenna. This increases connection speeds and network capacity without requiring additional antennas. PTP Backhaul For point-to-point backhaul, the Diplexer allows 5 GHz and 6 GHz PTP radios to share the same high-gain antenna. This increases backhaul capacity and supports faster links without adding more antennas. PtMP Sectors and Horns The Diplexer also provides greater flexibility when upgrading PtMP networks. Installers can transition customers gradually by replacing CPE during scheduled visits rather than upgrading the entire network at once. WISPs can also upgrade subscribers as they choose higher-performance service, creating a more economical and customer-driven migration path. Reduce Tower Space, Wind Load, and Rental CostsBy allowing multiple radios to share a single antenna, the Diplexer reduces the amount of equipment installed on a tower. Because tower space is often limited and costly, a smaller equipment footprint can help WISPs lower rental expenses or free up valuable space for future network expansion. PTP BackhaulThe Diplexer increases backhaul capacity by enabling simultaneous 5 GHz and 6 GHz PTP links through the same large, high-gain antenna. Operators can deliver higher-capacity backhaul connections without installing additional antennas. Greater Backhaul Capacity Increasing backhaul capacity strengthens the backbone of the wireless network and directly supports faster, more reliable internet service. The Diplexer makes it possible to expand backhaul performance without the cost and complexity of adding additional antenna infrastructure. One High-Gain Antenna, Multiple Links Combining multiple PTP links on a single high-gain antenna helps operators get more value from their existing infrastructure. Fewer antennas reduce equipment purchases, tower rental requirements, and initial deployment costs. Long-term maintenance can also be simplified because there are fewer components to inspect, align, repair, or replace. The result is a more efficient and cost-effective approach to expanding network capacity. Designed to Address Common WISP ChallengesLimited Tower Space Installing separate antennas for 5 GHz and 6 GHz radios takes up valuable tower space. The Diplexer allows both radios to share one compatible wideband antenna, reducing the equipment footprint and preserving tower space for future expansion. High Tower Wind Load Additional antennas increase wind loading and place more stress on towers, mounts, and supporting structures. By allowing two radios to operate through a single antenna, the Diplexer reduces antenna count and helps lower overall wind load. Limited Backhaul and Sector Capacity As subscriber demand increases, WISPs often need additional capacity without completely rebuilding existing infrastructure. The Diplexer enables simultaneous 5 GHz and 6 GHz operation through the same high-gain antenna, increasing available network capacity without requiring additional antennas. High Infrastructure Costs Every additional antenna can increase hardware costs, installation labor, tower leasing expenses, and ongoing maintenance. Sharing one antenna between 5 GHz and 6 GHz radios helps reduce both upfront capital expenses and long-term operating costs. Complex 5 GHz-to-6 GHz Migration Many WISPs want to introduce 6 GHz services while continuing to support their existing 5 GHz networks. The Diplexer allows both bands to operate through the same antenna, making it possible to migrate customers gradually without immediately replacing antennas or making major tower modifications. Maintaining Performance with Multiple Radios Combining multiple radios on a shared antenna can introduce signal loss and interaction between frequency bands. The Diplexer provides less than 0.6 dB insertion loss and approximately 30 dB of isolation between bands, helping maintain strong RF performance. The Diplexer will isolate received signals by 30 dB. However, when multiple radios share the same antenna, GPS synchronization is recommended to coordinate transmission timing and provide additional protection from transmit signals generated by the radios sharing the antenna. This is especially important in high-power or high-density deployments where simultaneous transmissions could otherwise increase interference. Typical Use CasesDual-Band 5 GHz and 6 GHz Deployments Connect separate 5 GHz and 6 GHz radios to one compatible wideband antenna to create a dual-band network that makes better use of available spectrum and increases overall capacity. Network Upgrades and 6 GHz Migration Add 6 GHz equipment to an existing 5 GHz network without installing additional antennas. This makes it easier to increase capacity while minimizing tower modifications. Point-to-Multipoint (PtMP) Access Points Operate both 5 GHz and 6 GHz access-point radios on the same tower sector through a single compatible antenna, reducing equipment requirements and simplifying installation. GPS synchronization is recommended when radios sharing the antenna support synchronized operation. Point-to-Point (PtP) Backhaul Links Combine 5 GHz and 6 GHz backhaul radios into one shared antenna system to support higher-capacity links while reducing tower space requirements and wind loading. Tower Space Optimization For sites where tower space is limited or expensive, the Diplexer allows multiple radios to share one antenna, reducing the total number of antennas required. Wind Load Reduction Projects Reducing the need for additional antennas helps lower wind loading on towers and poles, which can simplify structural requirements and potentially reduce installation costs. High-Density Wireless Networks In crowded RF environments, operators can use both the 5 GHz and 6 GHz bands through a shared antenna system to increase network capacity and gain greater flexibility when planning frequencies. For installations where multiple radios are transmitting through the same antenna, GPS synchronization is recommended to coordinate transmit timing and minimize radio-to-radio interference. Who Is the Diplexer Designed For?The Diplexer is well suited for: Wireless Internet Service Providers (WISPs) Point-to-Point (PtP) Backhaul Operators High-Density PtMP Network Operators WISPs Migrating to 6 GHz Tower Companies Wireless System Integrators Network Infrastructure Providers Rural Broadband Providers Enterprise Wireless Network Operators Managed Network Service Providers What Sets the Diplexer Apart from Other Industry SolutionsUnlike conventional RF combiners and general-purpose diplexers, the Diplexer is designed specifically for WISP networks that need to operate separate 5 GHz and 6 GHz radios through a single wideband antenna. Many diplexers are designed for laboratory, cellular, or lower-channel-count applications. The Diplexer combines low insertion loss, strong band isolation, and support for multiple RF paths in a solution developed for modern wireless broadband deployments. Purpose-Built for WISP Networks While many diplexers serve general RF, cellular, or laboratory applications, the Diplexer is designed specifically for WISPs using separate 5 GHz and 6 GHz radios with one compatible wideband antenna. Its architecture helps simplify installations and improve the utilization of antenna and tower infrastructure. Multi-Channel MIMO Support The Diplexer supports multi-channel MIMO configurations, making it suitable for high-capacity backhaul and advanced PtMP networks that rely on multiple RF chains and higher throughput. Very Low Insertion Loss Adding RF components to a signal path naturally introduces some loss. With less than 0.6 dB insertion loss, the Diplexer minimizes the performance impact of antenna sharing and helps preserve link budgets and radio sensitivity. 30 dB Isolation Between Frequency Bands Effective diplexers must keep different frequency bands isolated from one another. The Diplexer provides approximately 30 dB of isolation, helping separate received 5 GHz and 6 GHz signals while allowing both systems to operate through the same antenna. The Diplexer will isolate received signals by 30 dB. Because transmit signals can be significantly stronger than received signals, GPS synchronization is recommended for radios sharing the same antenna. Synchronizing radio transmission timing helps prevent one radio's transmission from interfering with another radio's receive period and provides an additional layer of RF coordination beyond the isolation provided by the Diplexer. Shared-Antenna Deployment Without a Diplexer, operators may need separate antennas for their 5 GHz and 6 GHz networks. The Diplexer allows both radios to share one high-gain wideband antenna, helping reduce tower space usage, wind loading, installation complexity, and maintenance requirements. Gradual Migration to 6 GHz As WISPs expand into the 6 GHz band, existing 5 GHz infrastructure can remain operational. The Diplexer enables both bands to coexist on the same antenna platform, allowing operators to introduce 6 GHz services gradually without immediately replacing existing antennas or significantly expanding tower infrastructure.
