Shure UC/SM58

I have several types of hf: shure (ULX Series pro and pro uc) and samson sennheiser uhf (Series 300). As for the pro uc, I only tie microphones (wl 183), but the receivers remain the same.
Advantages: very good door (mine are in a rack cabinet filled, without postponement or antenna amplifier), I've never known of a stall, and that's it.
drawbacks: the breath, which is very disturbing especially when plays or congress, or there is no noise in the room. I correct, but it's not ideal (low pass 10 kHz). There are not many choices of frequencies, and the display is very readable, but to see a channel number and a group is not necessarily essential. Moreover, without the correspondence table, hard to know the frequencies when adding other casual hf. The plastic housing is a little fake, but hey, mine are fixed and there is no problem. The markers includes: forget, moderately effective, and without landmarks. The antennas are half wave, and take up much space, unlike the 1 / 4 wave.
It may sound very negative, but remains still a good series hf, fairly cheap, and that works. The only big big problem is the breath. We can stick a reducer output, but when the number of receivers is large, it is the means. The ideal for me now is the ULX Pro Series, I have 2 sm with 58 capsules and 2 capsules with beta 87.
Voila, I hope I was fairly objective and clear, good luck in your research and make the right choice.
