Operating a multiband HF antenna covering 160 through 10 meters on a city lot can be quite a challenge.  In this video, Steve Ellington (N4LQ) shows us how a modified inverted L antenna, a counterpoise system, and a wide range antenna transmatch (i.e. "tuner") can simplify your task. Steve says he used 100-feet/30.48 meters of wire for the inverted L, a counterpoise system, and a MFJ-998 antenna "tuner" to get 160 meter to 10 meter coverage.  Hopefully, some of Steve's suggestions can help you get on 160 meters without too much difficulty.

If you can't view this video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=QAWZKKWumcY. An excellent, informative video tutorial on how to tune a magnetic loop antenna. In this case, the mag loop is the LNR Precision Loop, which has a tuning control built in at the base of the loop.  This loop is based on a design by W4OP.  This mag loop allows adjustments of the coupling loop which is critical for magnetic loop antenna design.

Installing a G5RV Inverted V Antenna for HF use on a Fishing Pole. Post #1333..

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=t6vI4nZMemM. The G5RV antenna is based on a design from Louis Varney (G5RV)(SK).  Originally, the antenna was made as a 3/2 wavelength antenna for the 20 meter band.  Over the years,  radio amateurs have modified the feed arrangement to allow operation on several bands, including 40, 20, and 10 meters.  Used with balanced feed line a 4:1 current balun, and a sturdy antenna transmatch (i.e. "tuner"), the G5RV can work other bands such as 15 meters. In this video, "kloxieman" shows us how he installed the G5RV as an inverted V using a 30-ft/9.146 meters fishing pole as the support structure.  His use of a balanced feed line, a current balun, and an antenna "tuner" gives this G5RV excellent performance on the 40, 20, and 10 meter bands.
