I've had Sergii replace a number of antennas for me over the last 12 months on different properties because he is reasonably priced and offers a great service and warranty for the price. I have also referred him to family and friends and would highly recommend him to anyone. When I was initially looking for someone to replace my antenna, most companies were just quoting over the phone on full replacement without even looking at the problem. Sergii was the only one who took the time to have a look. He is my go to AV person now. His knowledge is second to none.
