    Got it and assembled without any problem, however a simple assembly manual may be useful for the non expert (I am a radio amateur, so I am used to build and assembly antennas). It is not clear how to assemble the clamps, however I set them up one in a direction and the second one opposite to the first one and it' s holding. The antenna is now on top of a vertical pole about 4 meters above ground level. The coaxial cable which comes attached with the antenna is quite long, however I didn't measure it (yet); it is branded "SYWU - 50 - 5"; it is pretty rigid and stiff and BNC terminated. The vertical element (and the radials) is made of TWO sections, one screws into the other. The vertical element is 68.5 cm long and the three radials are 72.5 cm long. There are no trees or other man-made structures within at least 3 meters from the antenna. In these testing conditions, I measure the SWR of the antenna with an MFJ-259 Antenna Analizer and I find it is almost perfectly centered on 100 Mhz. At 100 Mhz I measure 1.0 SWR !!! At 101 Mhz SWR is 1.3; at 102 SWR is 1.6 and so on. At 99 Mhz SWR is 1.3 and so on. So, while the antenna does work as expected, if you need to transmit (say) on 88 Mhz) you will need to extend the lenght of the radials and of the vertical element. And that is a problem. If you need to transmit (say) on 105 Mhz you will need to "cut" few CM's of the radials and the vertical element. For AUD 50 including shipment, it's a good buy; if you do not transmit on 100 Mhz, you will need some expertise and instrumentation to tune the antenna to your desired TX frequency. Worth of note is the fact that the vertical elements and the radials are made of two sections; this means that potentially (I haven't tried yet) if I install only ONE element in each, the antenna will be tuned on a much higher frequency, possibly of use for radio amateur frequencies. I will test and comment again. Cheers for now. Stefano Mollo.

    This antenna could be paired with 5W FM transmitter sku 103051. For my first trial, the antenna was not enough placed high from the ground. So I could broadcast a radio program in a radius of 2 km. This received signal is perfect in a radius of 500 m. I'm sure I can increase noticeably the range if I place the antenna on the roof of my house.
