Not entirely true, there is no way that modded 10m (28mhz) radio gets all of the ham bands. The ham bands start at 1mhz and goes into the microwaves. You can open that radio to work on 11m (27mhz) the CB band illegally. Its hard to explain what we are able to do as hams. There is no one antenna that can do it all. Some of our antennas are only a few inches long up to hundreds of meters long.
antenna turner......I use an old Sigma 5/8 with a MFJ tuner works wonders..
