antenna is a portable end feed antenna in the field, weighing only 190g, portable and easy to carry. It adopts oxygen free copper vibrator with high emission efficiency. It adopts 1:64 balun to realize multi band natural resonance (7MB, 14m, 21m, 28m and 50MB). It supports a variety of erection methods, and the reception performance is 1-2s better than GP antenna. It is an ideal field antenna.\u003c\/p\u003e\n\n\u003cp\u003eDue to its excellent portable performance, it is very suitable for frequent outdoor activities, mountaineering, camping and field station erection. With QRP radio, it can often achieve good communication effect in the field. It is recommended that the erection height is more than 4m. If the erection height is 6m, the performance will be ideal.\u003c\/p\u003e\n\n\u003cp\u003eThe 40m long line is used with the fishing boat to make the storage convenient and fast.
