This is a portable mast system for temporary use. The base is a heavy duty speaker stand I got at a flea market. The mast is from MFJ purchased new. The antenna is a telescoping dual band type that doesn't need a ground plane. With some aluminum tent stakes and small diameter nylon rope I can guy this for use in light to moderate wind conditions.
In total the antenna is up about 20 feet. That gives an approximate calculated line of sight distance to the horizon of 6.25 miles.
The antenna is an AL-800. There are various sources for this antenna all with the same model number but seems to vary in over all length a bit.
