Hello, i just bought a radioshack PRO-2055 scanner, 25 mts of RG-8/U coax and a D-130J discone antenna. i will upload El Salvador“s ATC (ilopango aprt and comalapa aprt)ilopango airport is fine,like 10 km of my home wihout any important obstrustion,but the international airport that is 45 km away and with an obstruction hill of 450 mts, the ground communications sounds a little poor, do you think that if i get a higher mast for the antenna, the reception will improve? thank you
