    Good evening fellow hams,
    Are there any stateside hams out there who have used ZERO-FIVES wireline series (57 foot sloper/Vertical) inc 4-1 Unun/balun? and could enlighten me as to why a 100 feet + coax run is recommended and if so your on air experience with this particular length (57 ft) as sold by them Commercially.

    Best regards, M6AWG, Mark.

    Never used one, but from their description it sounds like a ground stake with a UNUN supplied, and 57' of wire with an end insulator. I have no idea why it's $169.:p

    They recommend 100' of coax if you're using a good wide-range tuner in the shack or 150' of coax if you're using an automatic tuner in your rig. That's to add some loss to the system so the tuner can match it. Hams feel good when their SWR is low, regardless how the antenna works (or doesn't work).:eek:

    Frankly, if you want low SWR across a bunch of bands, this old-fashioned design might be even better:

    With that antenna, you don't need to use a long coaxial feedline to make it match across a wide spectrum.
