Newbie Ques.
What cheap house hold stuff could I use to build an FM broadcast antenna.
Dave |
any copper wire, copper tubing, stainless steel welding wire, metal
electrical conduit, bailing wire, copper pipe, aluminum tubing, a TV mast, a wire fence, a metal gutter drain/gutter, a window screen, a vehicle (look at the rubber tires as "insulators", an existing TV antenna, a metal hand rail, etc.... The above are NOT in order of preference... I joke a bit here, but you get the gist of it... grin Warmest regards, John "Dave" wrote in message ... | What cheap house hold stuff could I use to build an FM broadcast antenna. | | | Dave | | | | |
How long or Big should I cut the wire or pipe to make a decent one? And what
should it look like? Square, Triangle in orintation? Something like this but Horizontal? | | o / \ / \ Or how should it be designed as "for distance" for a "whole house FM transmitter" to get it as far as I can?

That is a 1/4 wave antenna you have us looking at, a ground plane with
drooping radials--right? If you are just going to use it in a house, why not do a folded dipole out of 300 twin lead--with matching circuit, or j-pole? But, I am assuming (I know that's bad) it is low power and short distance, OR, are you going to try to cover your city? State?

Legally of course!
We received the "Whole House Transmitter" ( http://cgi.ebay.com/ws/eBayISAPI.dll...tegory=73 836 ) it's ok for about 50ft 'cuz of the obstructions. She likes it and now.. she wants me to transmit to the community pool so she can hear "her tunes" (about 2/3's of a mile away). I also have a small, 1 watt signal power booster(?) kit on order to boost the signal and would like to design an antenna w/o too much height or too noticable for this gizmo (deed restrictions!)

Dave:
Your question, while at first seeming simple to me, I now realize is much more complex. I looked at the ebay URL, and one "feature" of the device in question is: Q. Is there an Antenna? A. Yes, The Antenna is about 30" long made of thin flexible black wire I would have NO clue on how to match up any antenna and transmission line to that!!! Roy or another of the REAL antenna authorities are your best hope now... sorry... I am learning...

Wow.. I went looking on Radio Shack's Web site and the outdoor antenna's are
expensive... Were you referring to the Outdoor Antenna for UHF? I seen on the web somewhere that I could get an antenna for about $30 or $40 for something like someone earlier had said a ground plane w/ drooping radials.

Yea I know... it was cheap....
The near 1 watt kit I ordered I plan to "combine" the transmitter and pwer booster then attach an antenna...

Thats what the FM store where you bought your receiver sells you for 2.00 and if ;you want to transmit on it just cut it to frequency and get after it. Butch KF5DE |

Specifically... "Sec. 15.203 Antenna requirement. An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section." Also... "Sec. 15.239 Operation in the band 88-108 MHz. (a) Emissions from the intentional radiator shall be confined within a band 200 kHz wide centered on the operating frequency. The 200 kHz band shall lie wholly within the frequency range of 88-108 MHz. (b) The field strength of any emissions within the permitted 200 kHz band shall not exceed 250 microvolts/meter at 3 meters." So, if you add an amplifier, you will exceed the maximum field strength (by a bunch). Sorry to bring bad news. Good luck. John |
John,
Thanks for that info didn't realize the complications / legalities... Think it'll be ok if we just turn on the amp when she's at the pool and turn it off when we're not? I appreciate all the information given to me so far.

Locate the "device" in the attic? And, feed audio though a longer feedline?
