8 Feb Dear all. PLEASE I DO NOT WANT opinions on the performance of this antenna. All I want are some construction notes for this antenna, or any. New HF Antenna = Roomcap Before, all antennas were built accordingly the principle: Current in wire. This antenna is working with this principle: Current over . 14 Aug Ruehrberg-Loerrrach This is the Roomcap antenna, installed on the car. The size of the grid is 1m x 1m. This antenna works on all bands, from.

The location is to be considered as bad location for HF, as Duggingen is down in a narrow valley.

Direct ground mounting provides less signal strength. This antenna is working with this principle: April 30th 06, Well, my next question is, wntenna the antenna patented? It is like a religious thing for some people.

Here follows the received signal reports in S points: Visit antenna website Portable Magnetic Loop Antenna for 20m, 30m, 40m A simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres, but by changing the overall length of the wire coverage of other bands is feasible.

RoomCap Antenna Buck wrote: Switch to Threaded Mode. Given the size of the mobile Room Cap it should work quite well. Here is a link to the article: Imagine the loss of life or property that might occur if we started outfitting critical communication systems with qntenna antennas or antennas that do not work the way someone imagines them to work. How much is the value of this analysis? Interesting note during test on the romocap tile roof: February 10th 06 anhenna It provides no GAIN as com pared to other multi-section design.


Both antennas decoupled from each other and connected to the same transceiver via a coax switch. The detailed construction guide with supplier data roomap the components is available for charge. This one was called and the comparison test performed.

Fits onto a camera tripod. July 8, at 6: The size of the grid is 1m x 1m. The antenna wil be described after completion of the full test series. By using this form you agree with the storage and handling of your data by this website.

July Antenna comparison Microvert 40 m rkomcap On July 8th only a single QSO could be performed, comparing the Microvert antenna. Another senario is that the antenna proponent will refuse set up an experiment that has the potential to disprove his theory the ‘scientific method’.

July Antenna comparison with Microvert MV Felix, if you look at my post of November 8, you will see that I corrected myself.

He has not been with the magazine for nearly 10 years. The lower section is a conductor cut to resonant on Anhenna band. Please feel free to email me off list – my details are under my profile bit. But most people just comment without taking the time to get informed True small antennas have been introduced in AntenneX including my 9″ 28 MHz monopole ahtenna a 5′ end loaded dipole for 14 MHz.

Public demonstration of the antenna was here: Jack Stone is the only editor now. The best I can find on the antenna is a picture of what looks like a piece of PVC with a capacity hat on it. I am considering building something along these lines for use on the beach.


A new, revolutionary idea allows the construction of small HF antennas, which provide the same efficiency as large antennas. Again, part of the ‘scientific method’is that an experiment can be replicated by others.


Have you experimented toomcap all with this type of antenna? With car and mobile antenna I drove some m aside to be outside of the natenna, and the test could begin. We performed the tests while I was located at a parking place with my test antenna of 1. The comment was generally: Thanks for trying to send me the email. The test indicated, that in a roof installation the small antenna equals the performance “of the bigger brothers”.

After you so carefully protected me from receiving the minimum information on obtaining more information about the antenna, riomcap do I know you aren’t hiding something else such as a part you manufacture that I have to buy from you before being able to successfully build that antenna.

May 13th 06, December 01, I would like to hear from someone who has actually gotten your disc and possibly built the antenna so I can know how it performs from someone else’s point of view. If needed, it can be disassembled into a very small bundle no longer than the longest element. Once we know what is radiated we can compare.

Ask and arrange a date phone or e-mail to me.
