All the work I’ve done with this VPA is based on the PA0DRT Mini Whip design and I claim no originality for the circuit or, indeed, the format of the system. It looks like a two-stage amplifier with its input connected to a very small antenna element and its output to a receiver.

Fundamentals of the MiniWhip antenna Pieter-Tjerk de Boer, PA3FWM [email protected] (This is an adapted version of an article that I wrote for the Dutch amateur radio magazine Electron, January 2014.) A well-known active antenna for the LF, MF and HF bands is the "MiniWhip" designed by PA0RDT; see.The original mini-whip article by Roelof Bakker, PA0RDT states that the active antenna should be installed on an insulated mast, however there is evidence that the active antenna in fact uses the outside of the

Antenna Mini Whip La voglia di sperimentare mi ha spinto alla ricerca di qualche alternativa alla mini whip originale di PA0RDT. Son già due volte consecutive che mi perdo la trasmissione commemorativa della SAQ di Grimeton.
Building the PA0RDT Mini-Whip August 25, 2018 June 14, 2019 Merlin3d Leave a comment Since SWL is in one of my main interests, but I never had enough space to build a full-sized receiving antenna system, it seemed like a good idea to build something which takes up significantly less space.
pa0rdt_whip.pdf. Velmi zajímavé je také odlišné zapojení napájecí výhybky v poslední části od Alda Moroniho, s oddělovacím transformátorem. Ten je velmi vhodný pro přijímače přímo napájené ze sítě. U nás se první zmínky o Miniwhipu objevily v Radio revui v roce 2005. Zapojení bylo podle původního návrhu.
[quote][/quote] Hi all, I received my PA0RDT mini whip antenna from Roelof today, posted Friday, rapid delivery. Looks nicely made and good quality, I'll get it up this week, fed with lmr400 coax, looking forward to seeing what results it gives.
Zusätzlich zur Doppelzepp-Antenne habe ich nur noch eine sehr unauffällige Antenne. Eine reine Empfangsantenne für den Frequenzbereich ca. 0.5-30 MHz (Mini-Whip, PA0RDT). Die Mini-Whip brauche ich als zweite Kurzwellen-Empfangsantenne für den Diversity-Empfang (Phasen-verschiebung).

The mini whip absolutely goes crazy with over modulation and over loading in the room even near the window. I thought the mini whip was faulty. I put it up in the loft attic, and it was the same. Then I read about the mini whip = no no indoor antenna no no. So, I am planning to put it out in the garden.
Air tools are the choice of professionals thanks to their long-life and powerful performance. Air tools are driven by compressed air instead of batteries or electricity.

Oct 25, 2012 · The 2.1mm power jack is connected to a well filtered 12V to 15V DC supply. RX is connected left, the Miniwhip ant. is connected right. The antenna is RC coupled to the Rx, resulting in a constant sensitivity from VLF-30MHz. No transformer is used, as it is very difficult (impossible?) to produce with really 30kHz-30MHz wideband properties.
The pa0rdt-Mini-Whip. If it is accepted that a whip is a capacitance coupled to the electric field, shape becomes irrelevant, as long as the required capacitance is available. In practice the "whip" can be e.g. a small piece of copper clad printed circuit board.

Description The Mini-whip is an active antenna for the VLF and shortwave bands, the power supply could be fed through the coax with a BiasTee board.The Mini-Whip design has a frequency range of 10 kHz – 30 MHz. It is quite a cost-effective active antenna for SWL and DXers.
Изготовив Mini-Whip PA0RDT в точности по схеме, что выложена выше, (на КП302, естественно ) сделал следующие наблюдения. Пробовал удлинять "E-probe" - становится только хуже.
