Following a series of field tests conducted with two T-Deck devices operating on a LoRa/Meshtastic network, I evaluated the performance of the tactical antenna in both indoor and obstructed environments.
One of the primary test scenarios involved operating one of the devices inside an underground parking garage. This environment represents a particularly challenging RF scenario due to reinforced concrete structures, multiple walls, metal surfaces, vehicles and other obstacles that contribute to signal attenuation, multipath propagation and RF reflections.
Despite these conditions, the tactical antenna demonstrated a noticeable improvement in link performance and communication reliability. The tests showed that the antenna was capable of maintaining communication in situations with significant physical obstruction between the two devices.
Signal performance was evaluated using RSSI (Received Signal Strength Indicator), expressed in dBm, together with SNR (Signal-to-Noise Ratio). These measurements provided a useful indication of both received signal strength and overall link quality. Across different test distances and positions, the communication link remained operational and demonstrated consistent message delivery.
The main benefit observed was not limited to maximum communication range. In challenging RF environments, antenna performance has a significant impact on link budget and communication reliability. Even relatively small improvements in received signal levels, measured in dB, can increase the probability of successful packet reception and reduce the number of retransmissions required.
The antenna also performed well in environments where signal propagation was affected by multiple obstacles and non-line-of-sight conditions. The ability to maintain usable RSSI and SNR values under these circumstances is particularly relevant for LoRa/Meshtastic applications, where reliable low-power communications are often more important than simply achieving the maximum possible distance.
From a practical perspective, the tactical antenna provides a good balance between RF performance and portability. It is a suitable upgrade for users who require improved coverage, greater link stability and better performance in complex environments without significantly affecting the mobility of the T-Deck platform.
Overall, based on the RSSI, SNR, dB variations and distance measurements obtained during the tests, I consider the tactical antenna to be a significant performance upgrade for the T-Deck. Its ability to improve communication reliability in obstructed and RF-challenging environments makes it particularly suitable for LoRa and Meshtastic applications.
I would recommend this antenna to users looking to improve their RF link budget, increase communication reliability and achieve better overall performance in both indoor and non-line-of-sight scenarios.
