The Masda WA722TG is an unusual Omni Directional LPA designed antenna for use from 45MHz to 860MHz with a built in preamplifier. It is designed by Zhongshan Masda Antenna Appliance Co., Ltd. in China and was originally designed for VHF and UHF TV signal recption, but I have taken out the preamplifier which is housed in the plastic black box at the mast head since I only wanted the antenna for use with my VHF~SHF wide band radios and the amplifier would be a limiting factor to the frequency range and would in all cases overload the front end.
So the amplifier has been removed! The antenna is not of heavy duty construction and is of very light weight built, but at US$35.oo if it lasts for 2-3 summers then it is already enough. The antenna can be assembled in 5 minutes (not counting the amplifier removal).
