Fan Vertical Antenna - QRZ Forums
2019年1月11日 · Combing that with an antenna called a fan dipole, I wondered if I could do the same with some vertical antennas. As it turns out, yes you can. It's sometimes referred to as a fan vertical. Before I get too carried away. A fan dipole is an antenna that consists of a set of dipoles that are all fed from the same feed point.
How I made My Fan Dipole for POTA. - QRZ Forums
2020年12月1日 · I'm actually entertaining the idea of building and running a 6, 10, 15, 20, and 40-meter fan dipole myself at the QTH. I'm space limited, but not HOA restricted. I'm thinking a 33 foot push up pole on the wooden fence would make a decent inverted V.
The MFJ-1935 Cobweb antenna review and on-air test
2016年11月21日 · Not in terms of gain. The advantages of the Cobweb design over a basic dipole include: Multiband (resonance in the five highest ham HF bands) Compact (fits into area less than 3m x 3m) Relatively omnidirectional (also a liability; less gain; less quiet) A dipole can outperform this antenna on its resonant band in its directions of maximum gain.
What Went Wrong When I Elevated My 40/20 m Fan Dipole …
2024年1月27日 · I have been experimenting with my 40/20 m Fan Dipole Antenna for the past few days. My average reports on 40 m was 5,7 though occasionally I used to get 5,9 report. On 20 m, I could get a couple of DX and few VU contacts, with reports ranging from 5,3 to 5,5.

2019年1月12日 · Ah, the 'fan dipole'. So many articles on this, including the June 2010 QST. But the oldest start of print on this antenna concept that I've found has to be the short paper by Tim Shaw of the Radio Propagation Division of the USACEEIA at Ft Huachuca AZ around '68.
The MFJ-1935 Cobweb antenna review and on-air test
2016年11月21日 · The cobbweb antenna is not a loop antenna, but a group of dipoles (fan dipole) with their wires bent into a square shape. There are questions on this forum almost every day about bending the wires of a dipole. This is just one that is really, really, bent! You get some advantages and disadvantages -- compared to a straight dipole -- when doing ...
Issue #43 Trials and Errors: Building Out the Antenna Farm
2024年8月30日 · When I moved out, a 6ft Antenna Mast driven 4ft into the ground, and a Hustler Multi-Band vertical got me on the air at 6 different rental QTHs. It was awesome for an easy to install/Remove, and made a Landlord friendly setup. I am currently running an antenna I built over 20 years ago, a 3Band trap dipole now at 15ft.

2019年1月11日 · Great to see the subject of fan verticals come up here, but too bad the OP failed to include a proper vertical fan graphic and chose a horizontal fan instead. While I've only just begun reading this thread and don't know if this has been mentioned yet, but AJ6O has a beautiful ground-mounted two-band fan (20/40m) displayed on his QRZ page if ...

Ham Radio - The Doublet. An old but good multi-band single …
2019年12月9日 · My only antenna for HF currently is a doublet cut roughly for 40 meters and fed with RS 300 ohm window line and matched with an old Johnson-Viking matchbox - no balun. Admittedly, I'm no antenna guru but this antenna system seems to work quite well from 40M up to 10M. It will also tune up well on 80M but is a bit more persnickety.
