Coaxial cable dipole for 80m - Here are some simple antennas you can build along with calculators to help you get the right length.

QRP Magnetic longwire balun with VHF-splitter - This Magnetic Longwire Balun (MLB) makes it possible to efficiently use a coaxial lead-in cable with all forms of longwires, T-forms or other types of wire antennas, without the need for an antenna tuner.

Simple HF Baluns for 50/75 ohm coax - Show diagrams, winding methods and tables of some 1:1 and 4:1 baluns for 1.8 - 30 MHz suitable for use up to 200W (400W peak) on systems using 50 or 75 ohm coaxial cable input where SWR should not exceed 1.6:1.

Build a hanging dipole for 2 metres - Described here is a simple omni-directional, vertically-polarized dipole for two meters. Made from coaxial cable, it can be rolled up and stored in a small container

An Improved Multiband Trap Dipole Antenna - This improved multiband trap dipole introduces a new trap design and a change in trap location. The antenna features double-coaxial-cable-wound traps having lower reactance and a higher quality factor (Q) than earlier coax-cable traps by W8NX

CoaxTrap - This program let you design of antenna trap using length of coaxial line wound as solenoid on a coil former.

VE6YP CoaxTrap - The Coax trap program computes design parameters for the construction of coaxial traps for HF usage. Typically these are constructed from PVC tube and RG58/59 coax

Coax Monopole antenna - OE1MWW monopole antenna made with common RG 58 or RG 213 coaxial cable

Windom Antenna with 4:1 balun - The Windom is an Off-center wire multiband Antenna. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers .
