In stock. 1 THE OCF FD4 (FD3) WINDOM ANTENNA FD4 (80/40/20/10 m) The 4-band Fritzel model FD4 is a special version of a Windom antenna. It is a half-wave long .
So I did experiments with a FD3 for an added m range, see the schematic.
The target application for. See the seller’s listing for full details.

The lower the antenna the lower the impedance of the feed point.
Here are a few possibilities for fritzeel m antenna in the limited space. The SWR data for 80, 40, 20 and m, supplied by the manufacturer, are correct only if the antenna is installed in a straight line. Standard Shipping from outside US. Simple et efficace pourquoi bouder cette antenne. Learn More – opens in a new window or tab International shipping and import charges paid to Pitney Bowes Inc.
Finally he achieved resonance at and MHz and lengths of Analysis of the Input Current Component 3. The friitzel works as an impedance transformer, sometimes producing unfavourable impedance at the transmitter end.
It is necessary to experiment for the length of the ladder line. An octave bandwidth dipole antenna An octave bandwidth dipole antenna Abstract: You are covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing.
Have one to sell? For a while now I used a 56 meter foot long horizontal loop, hung up in our back yard. Add to Watch list Watching. The process with the transparent adhesive is for preventing that water gets inside the cable.

It worked satisfactory both at home and in Lebanon. Impedance Matching and Matching Networks. I figured as with the FD4, the FD3 should be able to cover 30, 17, 15 and 12 meters as well with use of a tuner. On higher bands it did not work well. Learn more – opens in new window or tab. frutzel
Anyone who wants an HF antenna that can be multi-banded, exhibits useful gain and directivity, is lightweight, has a small turning.
As described above, this increases the risk of feeder radiation. I found that a pF capacitor between the longer wire and the transformer brought the 3. Sensor and Simulation Fritzeel. It involves a GSM radio coverage. Also have the FD4,but no space enought to hang it up.
The latter consists of 25 ferrite toroids on the coaxial cable close to the feedpoint. If possible hang the m band antenna at right angles to the FD4. If proper matching and suppression of feeder radiation are taken care of, this antenna works as effectively as any other radiator of the same length and location.
The target application for More information. The vertical dipole and its electromagnetic equivalent, the vertical monopole Antennas can be classified in several ways. Add to watch list Remove frjtzel watch list.

Fritzel FD3 – PA8E
We need to take a “carrier” signal, identify a signal parameter we can modulate, More information. In this representation, the circuit parameters generally.
Application Fieldbus cable for More information. Use wire with good insulation. See all condition fditzel – opens in a new window or tab Subject to credit approval. Copying the dimensions shown above gave good results and saved me much pruning and reinstalling. The resonance of the antenna at about m height was close to 3.
I found that the so-called balun was not a balun at all but an auto transformer, with a direct connection between the outer of the feeder and one of the two antenna wires.

Fritzfl, much depends on local conditions such as height and metal objects in the vicinity. Fritzel,try it by yourself!
