   Very nice antenna. But i recomend too you the Diamond X510. It´s one of the best verticals on the market. Teste one and you will see the diference. I am using a 9 element yagi and the vertical sometimes it´s better.

   Try one…

   Like All J-Poles is has 0 dBd gain. – Of course there are better antennas for more money.

   Precisely. This antenna will not out-perform an antenna that has directional gain.

   There’s a big price difference too, which is why I suspect N7TFP chose it.

   Great review! Thanks. I’ve had mine since I bought it at Hamvention 2008, so threee years. It still looks pretty good. Not so shiny now; but no corrosion. It survived the big Windstorm with over 60 MPH sustained winds that tore roofs, siding, chimneys off houses. Didn’t have to touch the antenna.

   There are better antennas out there.. but No antennas out there for the money. Excellent value. I know several folks who love theirs

   I just got one of these today and put it up. I noticed that you put your on a wooden mast. I have a wooden mast, but put mine on a 5 foot metal Radio Shack mast. I did put black electricians tape where the arrow antenna is attached to the mast.

   I looked all over the minimal instructions and did not find a reference about a preference to wood or metal for a mast for this antenna.

   From what I’ve learned, it shouldn’t make a difference with a j-pole. I just did it because the wood was laying around…

   Hope you enjoy you’re new antenna!

   Thanks for the good review. I’m a newbie here. What ohm wire are you using? Can you use Beldin 9913 coax effectively for this rig? Also, while using an SWR Meter, how do you tune the antenna? Do the antennas adjust with a set screw? Thanks again. I’m sold.

    Any 50-Ohm coax should work. The antenna is not designed to be tuned. It has a low SWR for the 2meter and 440 bands.

    It doesnt seem to be built like a common J-Pole at all.
    There is no shorting stubb, and the 57″ and 6″ bars seem to be grounded, and only the 19″ driven. I dont see how this works 440, as there is no driven element for it besides a grounded one, but i guess it works.
    Im wondering if all was removed except the 19″ element, if it would still work?

    Inexpensive though, i may get one.

    Great review very detailed. I put one up also and enjoying the better range. 73 W6USC

    Thanks for the review! After 7 years, my Arrow OSJ 146/440 continues to work flawlessly. I suspect its operating principle is similar to half of an open sleeve dipole, which would make the coax shield part of the radiator. Winding about 8 turns of the coaxial cable into a choke balun at the feed point decreased my SWR to near flat on 440 MHz.

    Thanks for that tip… I’ll try that when I get a chance!

    my coaxial choke balun is actually about 4-5 turns and 8″ diameter like in the J-Pole YouTube video of EI5GLB

    hi mate,,great video!,,,how does this antenna compare to a normal j-pole?

    What is the minimum safe distance from a power line to allow when installing an antenna?

    a) Half the width of your property
    b) The height of the power line above ground
    c) 1/2 wavelength at the operating frequency
    d) So that if the antenna falls unexpectedly, no part of it can come closer than 10 feet to the power wires

    I love this antenna! I tried one out at a Field Day event and ordered one just days ago. I was told of a ham that co-phased a pair of these and got some impressive directional results. I’m not sure how you determine your forward pattern since the front to back ratio are probably identical.
