Simple Ham Radio Antennas

That mismatch is in the neighborhood of 1.5 to 1 without a "tuner".  With Folded Dipole Antennas, I've always used a "tuner" to be on the safe side. So, if you have some TV Ribbon and a length of RG-6 TV cable in your junk box, why not build a folded dipole antenna?  With a little luck, you

Rich Rodgers has come up with another way of using a stealth antenna in his deed-restricted property.  In this video, Rich shows how he positioned a vertical full wave loop antenna between some elevated bird houses to disguise his HF antenna.  According to Rich the antenna SWR is acceptable with an inline antenna transmatch (i.e. "tuner").  You could also use a 4:1 current balun between your antenna "tuner" and antenna feed to reduce SWR even further. I've used several full wave loop antennas on 40 meters using balanced feed line and a balun-"tuner" combination to give me multiband coverage.  Rich's project is simple and should get you on the with air minimum problems.  Just make sure HOA "enforcers" don't examine the bird houses too closely.  One could always use a telescoping fiberglass mast

Despite these limitations, hams across North America are making some fascinating contacts, often with homebrew equipment and antennas.  In this well-made video from Kevin Loughin (KB9RLW), we learn how to make a simple, inexpensive, and fun-to-use magnetic loop antenna for the 630 meter band.  Kevin says his design works and is eagerly pursuing more contacts on the low frequencies.
