Yesterday we discussed improving your signal from your handheld by adding an extension stick. Good audio is also important. If it's bad you can have a strong signal but still be hard to understand. Especially if the station you're trying to work is in a noisy environment.
Here I try different microphones with a cheap handheld with very different results. In some cases the microphones are sloppily built so the element doesn't always line up with the hole. So it sometimes pays to open them up to have a look inside.
