The MFJ-1621 Portable Antenna. This antenna will operate on 7, 10, 14, 21, 24, and 30 MHz. The maximum input power is 200 watts. In addition, a field strength meter is built-in for ease of tuning. With the MFJ-1621, you can enjoy operating your rig in remote locations (camping, motels, field day, etc). where a regular antenna may be difficult to set up and does not require a ground plane. Keep in mind that this antenna is not intended to permanently replace or outperform a regular full-size antenna (dipole, beam, etc). It is designed to allow you to operate when no other antenna is available.

The inductor of the MFJ-1621 is tapped to match the telescopic whip, supplied when it is fully extended. SWR below 2:1 can be obtained in most cases. Note that although the BAND switch is labeled for certain bands of operation, there will be cases where you will find that the minimum SWR occurs with the BAND switch set to a different band. This condition is normal.

Fifty feet of RG-58/u cable is provided to allow you to locate the antenna where it is best for operation. Keep the antenna clear from metallic objects and other obstacles which may interfere with operation.

Since RF is presented at the antenna, it is important that the plastic tubing be placed over the whip to avoid RF burns to bystanders. Also, it is a good idea to anchor the unit when it is windy.
