Antenna Tests

If you have thought about purchasing an antenna, you know that specifications can be hard to interpret. This is why the WLIO engineering department has been testing antennas to see if they meet the claims.

Quoting one of our engineers:

“Harry and I tested the Winegard HD-7694P.

The most interesting results for this High-band VHF and UHF antenna that we tested on ch10, then ch11 (in order to get away from local interference from our own ch8 digital signal).

This antenna shows very good attenuation of the side-lobes, around 25dB, and a front/back ratio of about the same amount, 24 to 27db.

It has a very sharp forward beamwidth that we have yet to measure, but I suspect it to be around 20 degrees (+/- 10 degrees) at the 3dB points.

We will take another look at it next week when we have more time, along with any other antennas you would like us to look at.

This antenna seems to be a rather good pick for a simple "in town" to medium fringe signal.

Later we will mount this antenna on the side of our tower to see how it does with a little height.

The "related" link will take you to a site to buy one, but as always.... shop around for best results and deals!
