What is tape antenna?
A: The Tape-Measure antenna is a simple, hand-held 2 meter Yagi; that is fun and inexpensive and easily to build. The tape measure antenna is a “home brew” 2 meter antenna made out of PVC pipe and a steel tape measure. The antenna is useful (especially if you want a portable antenna for back packing etc.)
How do I aim a Yagi antenna?
A Yagi antenna should also be pointed so that the largest fins are closest to the mast and the shortest fins pointed at each other. For Omni directional antennas, they should be in most cases pointed directly vertical. That is to say, pointed directly up into the sky.
What is the impedance of a Yagi antenna?
It is possible to vary the feed impedance of a Yagi antenna over a wide range. Although the impedance of the dipole itself would be 73Ω in free space, this is altered considerably by the proximity of the parasitic elements.
Does Yagi antenna need clear line of sight?
If there is no line of sight, a Yagi antenna will not perform well. Increasing the gain of an omni antenna results in less energy sent vertically and more energy sent horizontally, extending the range.

What is the best digital tape measure?
– Two-in-one distance measurement tool. – LCD screen displays the distance measured from the tape measure or the laser measure. – 165 ft range of the laser measure, 1/16 inaccuracy. – Automatic unit conversion between ft, ft – in, in, ft decimal, in decimal, and cm. – Two memory spots for holding distance measured for later reference.
