15m Projects - Antennas

Klik voor vergroting15 Meter Moxon by AD5UQ
Well, I told you I'd give it a try, so here is my version of a Moxon antenna. I had some 3/4" PVC pipe for the spreaders and a piece of thick Plexiglas for the center support.

Klik voor vergroting3 Half Wave 15 Meter Doublet (in phase) by KC8AON
For a good multiband ( 10 thru 40 meters ) antenna, try a 3 half waves in phase doublet for 15 meters.
It is derived by using the formula for the G5RV, but substituting 21 Mhz in place of the usual 14 Mhz.

A Light and Sturdy Quad for 10 and 15 meters by KA3PDM & W3/CE3VU
Fishin' for DX? A few fishin' poles and a hank of wire can help you snag the Big One!

Click to enlargeA Small Transmitting Loop Antenna for 14MHz and 21MHz by VK5BR
By definition, the small transmitting loop has a circumference less than one quarter of a wavelength. Because of its small size, it is possibly an attractive proposition for someone with inadequate space to erect a larger aerial.

Click to enlargeThe 10/15/20 Meter Trap Vertical Antenna by KGŲZZ
This antenna project came out very nice. It's a rugged homebrew multi-band trap vertical antenna that works the 10, 15, and 20 meter amateur radio bands. The antenna can be mounted on the ground or on a mast.

Click to enlargeThe Cylinder Dipole by PA1B
The cylinder dipole has proven to be a very small indoor HF-antenna. The cylinder dipole with two Monster energy drink cans and a coil is easy to build and is working fine on 15 m.

Click to enlargeThe HF Satellite Antenna by W4SAT
This is a no compromise dual band antenna. Instead of using traps, this design interlaces two separate antennas on one boom. This is a full size, four element beam on 10, and three elements on 15 meters!

Click to enlargeZLspecial antenna by JA6HIC
I made the 2el ZLspecial antenna at the same time as the QRP NO1transceiver in 1988. It was using it in the condition of 2el for a while. But, feeling the want of ability in 2el. I did the remodeling to 3el due to the performance up in 1993.
