## Overview

The TSA400 Ultra Wide Band Passive Antenna by RFSPACE is a high-performance Vivaldi antenna designed for 375 MHz to 6 GHz coverage. Built on low-loss PCB material and individually tuned, it delivers flat gain, low VSWR, and a clean impulse response, making it ideal for SDR, SIGINT, EMC testing, and spectrum analysis. Its large 19.5" x 15.5" size ensures superior signal reception, positioning it as the go-to antenna for professionals demanding precision and reliability.

## Description

The TSA400 is a new RFSPACE Ultra-Wideband (UWB) passive tapered slot antenna. These antennas are built on very low loss Printed Circuit Board material. Each antenna is guaranteed to cover the 400 MHz to 6 GHz + continuously. Each antenna is individually tested and tuned to cover the complete band. This is the ultimate broadband antenna for wideband SDRs. These antennas also exhibit a very clean impulse response with low ringing.

Review: Meets Spec and exceeds expectations. - Measured antenna transfer function using 2 antennas. Found it to be non-dispersive meaning suitable for UWB pulse applications. Verified RFSPACE data for gain and VSWR. Altogether an accurately specified and technically worthy product at a reasonable price point. happy to have found this supplier.
Review: Incorrect Dimensions - I am not sure where desertcart posted their dimensions from! The actual size of this antenna in the two largest dimensions is 19.5" x 15.4" not the product dimensions desertcart posted of 9.25 x 0.2 x 7.5 inches. This is a beast of a size; I understand the physics. No datasheet available on RF Space.

### ⭐⭐ Incorrect Dimensions
*by G***N on April 13, 2023*

I am not sure where Amazon posted their dimensions from! The actual size of this antenna in the two largest dimensions is 19.5" x 15.4" not the product dimensions Amazon posted of 9.25 x 0.2 x 7.5 inches. This is a beast of a size; I understand the physics. No datasheet available on RF Space.

### ⭐⭐⭐⭐⭐ Helpful UWB antenna for everything
*by L***3 on August 3, 2020*

Works great with U bolts to attach to poles. I've bought one for personal use and 6 others for work and they work wonderfully. The holes in the middle will also help with some of the wind load as well. You can add some silicone for additional weather proofing if you like as well as long as you are aware of how it might change your VSWR.
