Build your own 20m vertical  ^pop - Build your own 50ohm coax fed 20m vertical antenna, so easy a 9 year old can do it, or at least help! And the budget? You may already have the materials on hand, or worse case spend $15 by Andrew Daniel - KI4QFY

Coax cable dipole antenna for 10 Mhz - Coaxial Cable Dipole for 30 meters band by I2NDT with detailed pictures of his dipole antenna setup.

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.

The Guanella 1:4 balun - A cost effective current-mode 1:4 balun can be constructed from two lengths of coax, two ferrite rods, some electrical tape, cable ties, a length of PVC water-pipe and some connectors. This form of 1:4 current-mode balun is named after G. Guanella.

Coax Dipole Calculator - An efficient program to calculate dimensions of coax dipoles, or bazooka antennas considering velocity length of different coax cables. Express dimensions in feet/inch and meters/cm. Freeware by VE3SQB

Wire antenna with coaxial cable traps - This multiband antenna 10-80 meters is a home made project by I1BAY. Has been used for SOTA activations with great results. Traps are done with coax cable turns, dimensions are in the attached schema.

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

Types of Coax in Satellite operations - Coax is a very important part of a satellite station. It is almost as important as the antennas you choose.

Building Coaxial Traps - This page describes the design and construction materials W8WWV used to build a coaxial cable trap. A coaxial cable trap is a parallel resonant circuit that is usually inserted in an antenna element to enable multiband operation.

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 Traps from a Modeling Perspective - About Coax Traps, NC4FB examine the operation of coax traps through modeling.

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 .
