EQUALIZING PRESSURE USING MEMBRANE VENTS IMPROVES ENCLOSURE SEAL PERFORMANCE
protect seals on sensitive electronics against water, dust, dirt and liquids with rapid pressure equalization.
block contaminants such as dirt, dust or salts in changing environmental conditions.
rapidly equalize pressure also helps virtually eliminate condensation and reduce housing design complexity.
The VSWR measurements of this antenna are made at a height of 10 meters horizontally.
Antenna is top quality and performs perfectly. I'm enjoying a new band [30m] on FT8.
This is my 2nd antenna from Ron and wouldn't hesitate buying more in the future.
