good FM antennas

[Leigh_2]

I have bought a good Sangean Radio a few months ago and it' great, feels like an old classic radio. Just looking at it takes me back when radio was still great not the digital with suck.
Here's the thing, Do anyone know of a great indoor FM antenna that works

You've asked this before...

FM/AM radio antennas

Ever live in a location where the radio signal is weak, well i do. I had a digital radio and it suck, the antenna is a string like antenna and yeah, it only picks up the newer radio station but as for the weak ones it want. So i bought a vintage radio from Amazon.com and it works great. i bought...

Any tiny indoor antenna will be weak.

Go make yourself a dipole antenna tuned to the frequency you need for that preffered station.

You can use shielded cable 75ohm aka tv cable. (but it gets a weird t-joint hard to make.. so the speaker wire is an easy route but not perfect). If you need max boost, go with 75 ohm cable and keep the dipole straight in a pvc tube with a T splitter in the middle to keep the cable straigth, or ziptie it to a stick.

You can calculate the actual wavelength of the station here: http://www.onlineconversion.com/frequency_wavelength.htm

Tip: do not tie knots at ends, keep the antena in a PVC tube with caps and secure with hotglue. Add a pvc T fitting for that pvc tube in the middle to keep the diplole apart and at 90 degrees (also a add a piece of pvc tubing in the middle T fitting to keep the main cable away and perpendicular to the dipole antena). Add shielding (tinfoil wrap, aluminum tape, a coil of copper wire wraped around the wire, etc) for the part that goes from the radio to the T-split in the dipole.

Finetune the length by having the possibility to move a bit the T-split (or by cutting bits off the ends of the dipole a bit at a time.. but careful not to overshoot the desired frequency)

Dipoles can be made 1/4 wavelength (roughly 1.5m in total), or 1/2 (3m total), or go crazy with full length at 6m
If you have the vertical space in a yard you can go monopole with any heigth you want. like 4 x wavelength at 12m.


Keep in mind, any bought tiny antena will not be tuned to your specific frequency exactly, and here size matters. Regardles of marketing or price, or brand, a tiny antena is weak, and an ordinary speaker wire dipole will be better.
