Приветствую тебя! Да, антенна super! В городе показала себя на 100% . За городом не испытывал, но думаю нужно будет ставить малошумный усилитель. в любом случае - благодарю.Если появиться что-то интересное, пиши, сделаем!

Greetings! Yes, the antenna is super! The city has shown itself to be 100%. Outside the city did not feel, but I think it will be necessary to put a low-noise amplifier. in any case - thank you. If there is something interesting, write, we will do it!
