What do you want to use the antenna for?
General listening, mainly airband, mainly radio amateur bands, mainly marine??
Also where do you want to use the antenna?
I have used those micro mags for years, as my scanner antenna of choice for my car.
For home base use there are much better options & for out & about handheld use other options.
Also if it's for homebase use, do you have any limitations on what you could use?
I am not in general a fan of scanner vertical antennas such as the one linked to above, but I am a fan of Sanpiper antennas. I have several of their antennas & all have been well made & value for money.http://www.sandpiperaerials.com/
