Whooshing sound
#25

Between TVs, Digital TVs, CFL and LED light bulbs, computers, cell phones and the remote readable electric meters, AM is a horrible place. I used to have an article on magnetic vs electrical interference, but, of course, I can't find it. (It may have been from the Phorum.) If you use coax as a lead-in, the length and style may be important to have the correct standing wave ratio. You may also have to create a matching transformer. You HAMs, please jump in as this is a little outside my wheelhouse.

I have an Inverted L Antenna, running from my shop to a tree about 75 Ft from my shop, at about a 45 degree angle from NYC, where the vast majority of the AM Stations in my area are located. This, along with a water pipe ground does work well, even though it is not directly aimed at the city and the tree is southeast from my shop. I am due east of the city.

In addition to a good outdoor antenna, a good "Hopkins" filter is useful. These are available on the "bay" or can be scavenged from newer CRT Type TVs
