A very small (approx 1m) base antenna which can be used indoors or outdoors. Supplied with bracket and u-bolts.
This antenna will give very poor performance compared to other base antenna, and really is a last resort if you can not fit anything else. There is no groundplane required.
Expect a range of about 4 miles if mounted outside and possibly about 2 miles in the loft.
Swr is adjusted by changing the length of the coax. A cutting chart is provided and you must use the correct length of coax as listed (roughly multiples of 9ft).
