HyEndFed Dualband for 40 and 80 meter.
With this antenna you can tune 40 meters separately to the desired frequency with the lowest swr.
You do this with the wire (stub) that hangs down vertically in the middle.(around 2.5 meters long)
Power : 2000 Watt PEP, SSB
Length : 40 meter.
Enclosure : Polycarbonate IP67, 100% UV resistant.
Aluminum mounting plate 5 mm thick.
SO239 Teflon Connector.
All hardware Stainless steel.
No radials or tuner neede.
With a vent plug
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.
This is the second antenna I have ordered from Hyendfed as it is best so far. The build quality is rugged and heavy duty, the parts are top quality , I expect no corrosion and years of service just from looking at it.
This antenna replaced a 80/40 Bazooka dipole that was just not performing well, I also live in an area with a high amounts of noise on the lower bands. This antenna has better signal properties than my old Bazooka and a lower noise level, my noise level has dropped from 9dB to about 3dB while retaining signal strength.
The antenna easily takes 1Kw of power from my amplifier, I have the antenna paired to a Highendfed low band line isolator which elimInates all noise coming back into my shack. The antenna was easy to tune, I managed to get both bands to an SWR of under 1.5:1 very quickly.
Thank you again for a great antenna.
