WE are back on the blog, with photos of a Terrestrial antenna being mounted on a mast, and raised skyward. We needed to do some more testing, so we mounted it next to a Universal flat line 300 VHF antenna, that is uni-direcional, and has almost zero gain. We use the ufl300 to tune in HD TV signals and get signal strength readings all the time.
So we thought a good side to side comparison with a Spiralcone Terrestrial unit would be of good value.
We already know two things- the SCT is very directional and exhibits high gain at certain frequencies. On the bad side, we have the SCT connected to 30 feet of coax cable, and that will kill some signal strength. We have the same amount of coax on the UFL300, so no diffo's there.
Here is the NO UAV's over my house decal, on a stainless reference grid . it just extends the area of the "white dounut"which is the first grid in back of the antenna cone. We added a second grid 16 inches away, it was an experimental grid we had laying around in the shop. It was painted bright green, and already had a decade resister on it. So we put it to work.
