Rated 4 out of 5 stars

Received the RF Shielding Room Signal…

Received the RF Shielding Room Signal Line Filter, rating ≥3000 VAC dielectric strength and humidity tolerance to 95 %RH; really tough build and great for harsh environments. Slightly heavier than expected, but works perfectly in our noisy setting.
