An basic horizontal half-wave antenna which can be made of ordinary copper wire. The cable should have a cross section of 1 mm 2 or more. The antenna can be stretched between two masts, a house and a mast, or between two apartment buildings. -
Use this online calculator to determine the length of a quarter-wave antenna from the frequency. Both metric and English units of measurement are supported. -
The collinear J-Pole, often known as the Super-J, does improve the behavior over a regular J-Pole. As many attest, there is an advantage when vertically combining 1/2 radiating sections to have a bit of separation between the half-wave end points. The Super-J has very little separation between the two half-wave radiators. -

Dimensions and EZNEC plots for a 2 Element 30 meter Yagi antenna with 28 Ohm featuring 4.3 dBd Gain and a 16dB F/B with a good bandwidth. -
Most people think it's a good thing to have and the more the better. However, this is not always true - and the amount of gain is often not what it appears to be. Assuming higher gain is what you need, how do you determine what will give the best performance? -
