| I'm planning on using this in the field for my POTA setups to gain more efficiency from my temporary antennas. Not sure carrying around a Smith chart is practical. Which of the two testers would give me more useful information? Thanks |

| I have recently resurrected my old MFJ-204b antenna bridge/analyzer. It measures Resistance and resonance frequency. I also have a YouKits FB-01 that measures Impedance (z) and SWR. I typically have been using the FB-01 to test my portable and station antennas at the coax end by the transmitter, but I want to get more precise by adjusting the antenna at the feed point. Would it be better to use the MFJ and measure resonance and resistance or use the FB-01 to measure SWR and Z. I've read all kinds of stuff about this and frankly my head is swimming. Any thoughts or info would be greatly appreciated! Bob KT8DX |

| Likewise, mine works pretty well. I had it mounted on a 17 x 17 foot chain link fence and got out well. I currently have it ground mounted on a post sunk into the ground and performance isn't quite a good, but still acceptable. I'm planning on running some radials to mimic the fence to see if performance improves. Note that this is a compromise antenna from beginning to end. With that being said, it does work and is often the best, if not only solution. Hope this helps. | ||
