herez what u gt to do
1st ull have to 1st calculate the length of the cnducators for the antenna..
decide what is going to be ur primary radio station >>
for eg i listen to Radio mirchi at 98.3MHz so i need to design my antenna for 98.3 Mhz..
so the calculation for lenght of the antenna is:
wavelenght of the fm frequency / (divide by) 4 = 1.18x 10raise to 10 / (divide by 98.3 x 10 raise to 6)
wavelength is calc by dividing the speed of light by the frequency of the fm signal.. thts all noted on thlink i have given u..
so in my case it comes to 1.18x 10raise to 10 / 98.3 x 10raiseto 6 (frq in Hz)
------------------------------------------------
divide by 4
in my case for 98.3 the length comes to approx 35.42 & in the link i have given u he used the 88.5 frequency & he got the length as 33.34
so now u if u too want to listen to radio mirchi @ 98.3 fm then get the copper wire i mentioned above cut it into 2 equal parts of 35.42 inches
stick it to the wall harizontally like this:
==================a b==================
. .............35.42 inches | | 35.42 inches
. ...............................| |
............................... .| |
............................... .c d
connect a good quality wire to 'a' & 'b' .. the other ends of the wire i.e.
'c' goes to the antenna & 'd' goes to the -ve of the battery connector(or the power supply)
this shud surely give u better signals.. now u can adjust the atenna for better position .. i mean right now u have it stuck on the wall horizontally u can move it 360 degrees >>>> & find the angle where u get best reception >>> & stick it to ur wall to the best angle.
IMP: dont forget to ignore those crazy looking dots in there .. they dont let us put spaces in here..& i im bored to attach a picture ...
btw do u get fm channels in heaven ??
