![]() Needless to mention that both mentioned documents are already largely published over the Internet. ![]() If you which to learn about the details of this intriguing achievement, see Roelof Bakker explanatory document of his active mini- whip and find here the schematic of the antenna. Overall, the performance of the pa0rdt mini- whip is somewhat remarkable for its size and furthermore, with a very low noise floor but it is obvious to me that it wouldn’t replace a Beverage antenna by any means. One thing I noticed and which I can’t explain until now is that peak around 700 KHz coming from the whip, which happen to be a notable rise of the noise floor over that specific portion of the spectrum. The Mini-Whip at University of Twentes (Netherlands) Remote Receiver. Now, for Trans- Atlantic mediumwave DX which is my main interest, signals are hardly showing up on the whip with no surprise given my inland location. Much more information on the PARDT e-probe antenna may be found here in a. It is quite a cost-effective active antenna for SWL and DXers. ![]() Nevertheless, with some little help of the RPA- 1 preamplifier, Roelof Bakker’s pa0rdt mini- whip managed however to bring some decent competition to one of my Beverages as shown on the above screen capture, using HFSpan on a 0- 10 MHz scale. The Mini-Whip design has a frequency range of 10 kHz 30 MHz. ![]() As previously mentioned, I was sceptical about the mini- whip performance given the fact that I’ve been used to work with long Beverages for years. ![]()
