I don’t know many hams nor do I chat with the same hams on a recurring basis, and my wife is only tangentially interested in radio inasmuch as it makes me happy, so I thought I’d be the life of the party and post about the best day on the air I’ve had yet. My aim is to share my enthusiasm with the world.

I’ve been a ham for about a year. I’m young (experience-wise) and still learning. Until this weekend I’ve been using a portable whip on my balcony combined with my President Lincoln for 10 meter contacts. My antenna mounting situation was awfully complicated, so I often left the antenna mounted several days at a time such as on the weekends. This finally bit me when the fine women who were feeding the squirrels next door moved out. The squirrels went ballistic and destroyed my antenna along with wreaking havoc on the rest of the neighborhood. They chewed through the loading coil and the coax! Preposterous. I cannot imagine what they thought to gain from doing so. Nevertheless, it put me out of commission for a while.

I think the math behind magnetic loop antennas is really cool, and I don’t have much space, so I decided to try the Chameleon F-loop as my next antenna, the base model. Wow, did I have so much fun today! Tuning was tricky because of that high Q and narrow bandwidth, but I didn’t realize how active the airwaves could be when you can hear clearly. My reception was so much better because my noise floor seems to be lower with the mag loop compared to the whip. I also enjoyed the directionality of the loop, giving me a new property to play with to get the best reception.

Thanks for reading!

    It’s crazy how much I can hear now. I lost a full S point on the noise floor and the bands are always busy when open. It seems like it’s immune to my local RFI.

    FT8 on 10 I would usually see a few stations. Now, sometimes I have to actually look for a free slot because I’m hearing so far out there.

    I read that loops can be better beams than a four yagi if mounted too low to the ground not on a tall enough tower, which is an easy mistake on lower bands.

      And if you know the direction of your rfi just turn the loop so the null (sides) face the rfi and it falls off like a rock. The signals are sent and received on the edges of the loop of course
