Finally got my dipole up on a 45' MFJ fiberglass pushup mast today. Nothing special, just a 130' dipole fed with 450 Ladderline straight into an old MFJ  986 Differential T Tuner. Tunes just fine 80 to 15 meters. And best of all, NO interference...........yet!

    James you are a lucky man! I still have massive peaks at 14.030 and other places. I need to find time to find them.

    Nice! Nothing like using the inverse square law to your advantage.

    Power density of a signal is proportional to the inverse square of the distance from its source.

    Or, local QRM decreases by a factor of 4 when distance to it is doubled. Getting away from noise sources pays dividends very rapidly.

    Thanks for that George! Now the comment makes far more sense.

    Thanks, George. I am familiar with the inverse square law but not sure what you were referring to here regarding James antenna.    I thought you might be kidding him.   I'd have made reference to rattling the either myself.  HI HI    73, Jim

    Arrgh... this falls under the category of stuff I used to know but long forgot until I have to use it again at which time I become great friends with Google.

    I did! And you never came back to me! Of course, you may not have been on the air at the time I did transmit! :-)

    Thanks! It only took a couple of months to get things together and then get the time to put it all up. Still have a vertical I plan to put up as well.

    George, it helped a lot! I'm amazed that I have no "noticeable" interference from my neighbors electronics. Another benefit, I reconnected my Bose speakers and no spikes showing from the **** wall wart!

    How many guy lines does that mast require?
    Which model is it?

    The instructions suggest at least 2 sets of guys. It's fastened to the back of the house as well. I don't remember the model number. But, it is the 50' heavy duty model. Overall, it was easy to install. Just right for an inverted V. James WD5GWY
