WISP antenna comparison on Ubiquiti LTU Rocket with RF Elements TP horn vs IsoHorns WB6-A90 vs LinQ

David with IsoHorns provides an analysis of a future antenna comparison test that will be conducted by Chris Johnson, a Wireless Internet Service Provider (WISP) operator with SkyNet Communications, serving Bozeman, Montana. Chris is doing many tests on various WISP gear and is an active member of the WISP community on the Facebook group WISP Talk, and hopefully soon WISP Group 2.0! In this video, I share my thoughts on Chris Johnson's upcoming WISP antenna test. I anticipate that our horn will perform exceptionally well with Ubiquiti LTU radios. However, the IsoHorns WB6-A90 is designed for Ubiquiti airFiber MLO MultiPoint radios, which are not yet available. The antennas being compared are the RF Elements TwistPort horn, IsoHorns Wideband 6 Ghz Asymmetrical 90° Horn Antenna (WB6-A90), and a LinQ antenna, paired with the Ubiquiti LTU Rocket radio, operating predominantly in the 5 GHz frequency band. The IsoHorns WB6-A90, which arrived later for testing, is particularly highlighted for their potential benefits in noise reduction and scalability within WISP networks. This video delves into the technical aspects of antenna performance, focusing on factors such as antenna gain, noise rejection, and frequency range. It emphasizes the importance of horns over sectors in terms of reducing the noise floor and enhancing signal-to-noise ratios, which is critical in dense network environments. A critical comparison is made between narrowband and wideband antennas. Narrowband antennas are noted for their tuning within specific frequency ranges, which can lead to enhanced performance. However, the benefits of wideband antennas, such as the versatility across a broader range of frequencies, are also discussed. The WB6-A90 is designed for Ubiquiti AirFiber MLO MultiPoint radio, expected in early 2025 across an even broader spectrum, particularly within the 5 GHz to 6 GHz range. This video also touches on the implications of antenna performance on network design, pointing out the differences between replacing one antenna in a network versus replacing all antennas. The latter could influence the overall noise environment and, consequently, the network's performance. This video serves as a resource for WISP professionals seeking to understand the nuanced performance differences between various antenna types and their implications on network efficiency and scalability, particularly in relation to popular brands and models within the industry such as Ubiquiti, RF Elements, and Cambium’s ePMP 4600L and ePMP 4500L.
