Ground conductivity is a fascinating subject and good ground conductivity near salt water can lead to some expansive coverage areas. One example was 630 AM CFCY in Prince Edward Island, Canada. With 10.000 watts they were listened to in 5 of Canada's provinces and places in the states. 720 AM CHTN had a similar powerful signal. PEI soil is filled with iron, hence very red and highly conductive. As soon as the ground wave hits salt water the signal becomes even stronger. Sadly both AM powerhouses were replaced with one lung FM signals. Now the same stations cannot even cover Prince Edward Island. Irony is an incredible thing. Tecsun, Sangean and other Chinese companies are building AMAX quality wide bandwidth type receivers. Broadcasting is filled with Foolish CEO's who kill technology without understanding what they destroy. My slogan, AM Radio is so much better than you think it is.
AM’s audio quality and vulnerability to noise make it a non-starter to anyone under 50. Kids don’t own radios anymore, and are used to clear sound from internet feeds such as podcasts and streamed music. The capper is nearly zero interest by major advertisers in buying broadcast spots on the AM band.
Sure beats making a slit with a spade and pushing in the wire with a piece of plywood!
So my pizza cutter and a stick are not an approved method?
Curious, what was wrong with the original ground field?
What is the useful life of a buried radial? A friend of mine worked at a station near the railroad. He tied some to the tracks. The station moved transmitter sites and the tower is gone. It’s odd seeing that after it had been there for 60 years.
They play a large role in ground loses and final power output. In areas with poor ground conductivity and no radials, you might lose 65% of your power to ground loses, and maybe not even have an antenna that will even tune.
Thats awesome.beats a trench shovel😃
What AM station is this ?
How many and how long?
Is there a ground screen connected to the tower base?
Well, what do you think?
@@kenjohan why don't you tell him and don't be so childish.
You've done this before, I can tell... LOL!!!
Hi can you show the actual and proper installation of 120 pcs radials connected to the copper strapp of the grounded tower and also the actual installation of ground rod and lightning dissipator for the tower. For our reference. Thank you very much
I was thinking the same thing. Not only that Am works best in wet area's that's why they always in swampy places. not in the middle of a dry desert. The station I worked at had 4" strapping welded with a metal screen 2 ft down in a wet area.
