MFJ-1622 Apartment Antenna

Image
  If you live in a deed-restricted home or apartment, you may find the MFJ-1622 useful in getting on the air.  Mark Elzey shows us his MFJ antenna and explains how it works. I have used this antenna during the past and found it a workable compromise for HOAs and CC&Rs. I improved the performance of this antenna by replacing the stock feedline with RG-8X and by using a better counterpoise.
