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.
yesterday I have resceive my new 40m Hyendfed (QRO 2KW PEP). I have install it today 5 meter up my Metalroof from the house and the end from the antenna is going to a tree also 5 meter up. I have only cut 15 cm from the line. My SWR is perfect. At 6.850 Mhz ( 1,5:1) . On HAM-band 7,000 Mhz (1,0:1) and the end of the band 7,200 Mhz (1,0:1). On 7,300 Mhz I have also excellent SWR (1,5:1) always with OUT tuner ! Today at 17:30 UTC I have make my first contact with YB7OO with signal 5/8. I use also a Hygain AV640 , but it is a big different between my Hyendfed. Signals are in all directions always 1-2 signal streng better as on Hygain. Also I have not so strong Noiselevel and QRM. Excellent Antenna performance. I use also since two years ago a 80m (QRO) Monoband who make's me also happy. Nice Job from the HYENDFED-Team. Regards from OE5RAL Andy
