Very good price / quality but it must adapt and tinker around: - It must take active part in changing the dipole and the cord on this condition we can be closer to 13dBi. - In terms of the guiding strands, it is necessary to block using quotation or fine points. - The addition of a rear reflector, will improve the overall gain. Finally, a base for a good directional antenna. If you put off DIY, prefer a dipole 6 to 8dBi to be sensitive.
