I bought a Pixel RF-PRO-1B a couple of months ago and put it up on my roof.? I use it with a QS1R software defined radio.? I am very happy with it.? For me, it works as well as a resonant dipole at any particular frequency, but it does this from below 500 KHz to over 30 MHz.? Also, it can be rotated if needed to null out a noise source.? If you are only going to have one antenna to monitor the whole HF/MF band, get this.
