Antennas : 160M

  • G3YXM Small Loop - This simple antenna is capable of remarkable results on 160, 80 and 40 metres. Forming a triangle from around 50 feet of satellite TV coaxial cable, the top of the triangle can be as low as 15 feet, and the lower side just high enough to prevent a passer by hanging themselves

Antennas : 30M
  • 30m vertical dipole - The 30 Meter Vertical Dipole is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoint uses a T-section of PVC pipe. The coax loops through the PVC pipe to provide strain relief. by W1TR

Antennas : Antenna Calculators
  • Corned Fed Delta Loop - Author found a ratio between the lengths of the sides of the Delta Loop that give reasonably low SWR into a 50 ohm coaxial cable almost independent of the high above ground and other surroundings. This ratio also gives good results no matter orientation. Includes an online delta loop antenna calculator.

Antennas : Baluns
  • BalUn for Delta-loop & Quad-loop antennas - This Guide helps you to build the 1:2 BalUn 600 Watts DIY kit step by step. If a delta-loop or quad-loop antenna is powered with a coax cable from the transceiver it is necessary to use a 1:2 BalUn. This 1:2 BalUn uses a symmetrical 1:2 impedance transformer.

Antennas : Baluns : 1 to 1 Balun
  • A Cost Effective Current-mode 1:1 Balun - A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors.

Antennas : Delta loop
  • 160m Inverted Delta Loop - This 160 meter Delta Loop antenna is made of Hard drawn copper wire AWG 10, the two upper side are 148.5 foot each base wire is 240.9 foot, the feed point at 30.69 foot to one corner, feed with 450 Homs balanced line to an antenna tuner on the ground, then with 50 homs coax to the shack.

Antennas : Feed Lines
  • Feeder Radiation - Connecting centre fed antennas, dipoles, yagis, rhombics, loops to coaxial cable, unless care is taken, it is not difficult to end up with feeder radiation resulting in power loss and the radiation characteristics changes

Antennas : Loop
  • A Small Wire Loop Antennas for 160 meters  pop - Low noise, receive only coax loop antennas for 160 - 10 meters HF bands

  • Cheap antenna to make from 160m - 6m  pop - The antenna is nothing more than a simple 2.4 metre square loop drawing pinned to the internal brick wall of the spare bedroom. Yep, thats right, the inside wall of the spare bedroom - ideal for flat dwellers, hotel rooms or whinging neighbours, The loop has a simple switched inductance at the top of the square loop and uses a simple coaxial stub to tune the antenna. An additional variable capacitor placed across the feedpoint can be used to fine tune the resonance of the antenna, by Andy G0FTD

  • Horizontal Loop Antenna Experiments - The HF horizontal loop has been around for many years now. This article includes a YouTube video and discusses the reasons for looking at this antenna, its design, and its installation. There are some on-air comparisons against three regular double bazooka (coax) dipoles and the Par SWL End-Fed antenna.

Antennas : Magnetic Loop
  • 160/80m Coaxial Receiving Loop Antennas  pop - Receiving loop antenna for top band. This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter. And made of light weight material. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable.
