It is not always convenient to operate an FM receiver, whose antenna is a meter long piece of wire, and in some cases it is sometimes impossible. To add comfort while listening to the radio, the author of the channel “Valery Samodelkin” shows how to build a miniature, helical FM antenna that has high sensitivity, looks stylish and does not cause any hassle in its placement.
It will take
- Permanent marker.
- Bolt 6×150.
- 2 nuts and 1 union nut.
- Heat-shrink tubing.
- Insulated wire 77 cm long (distance 1/4 FM wavelength).
- Protective cap from the lamp base (they are thrown away when buying).
How to make an FM antenna from a marker with your own hands
We take a marker and use a clerical knife to cut the upper part of the digger.
As a result, the upper wide ring falls off and a pointed surface appears.
We disassemble the body, remove the ink rod. Trim and remove the writing tip.
The assembly kit is ready.
We drill the bolt with a 2 mm drill in the middle. We put a heat shrink on it to close the part from the cap to the hole.
We insert the wire with its bare part into the hole and twist it for good contact. We wind the insulated part of the wire a turn to a turn on a bolt on the side with heat shrinkage.
Drill the back cap from the marker and the protective cap from the light bulb in the center for the bolt.
We collect the antenna. Insert a bolt with a wound wire into the marker body.
We fix it with a nut.
On the one hand, we glue the narrowed cap on the super glue, and on the other, we put on the cap from the light bulb and fix it with a long nut.
We erase the name from the case with a solvent.
We paint everything black.
Install on a motorcycle.
The reception is excellent! Even turning the steering wheel does not interfere.
This antenna is much more sensitive than a conventional long piece of wire.
Such a mini antenna can be made not only for a motorcycle, but also for a car or just for a home music center.
