Weird antenna idea # 492
Ok Slinky lovers...you may leave the room now. This idea may just work and work well. We've all lain awake at nights thinking how much better life would be if we just had a longer antenna. A retractable/adjustable one is even better. Something you could adjust to wavelength easily would just pure icing on the reception cake. problem SOLVED A super long metal retractable TAPE measure! These come in various lengths. I accidently broke the end off my hundred footer yesterday and that started the thought process. I also noticed that the replacement tape 'ribbon' costs more than a brand new complete unit. Stupid. A METRIC tape would be marked in ....wait....METERS. Quarter wave length, half wave length? No Problem! This antenna has the measuring means BUILT RIGHT IN! I now just have to figure out how to get someone to hold the far end while I'm at the radio... mike (now wondering if the whole world has already thought of this but neglected to inform me.) mike -- __ __ __ __ __ __ __ __ / /\ / /\ / /\ / /\ / /\ / /\ / /\ / / / /\ \/ /\ \/ /\ \/ / /_/ \/_/ \/_/ \/_/ \/_/ \/_/ \/_/ \/_/ ..let the cat out to reply.. ©Densa International 'Think tanks cleaned cheap' |

Someone thought of it b4. I own a surplus variable length dipole that uses metal measuring measuring tapes. Coax fitting is built in. Works well for a camping antenna. darn. nothing new under the sun as they say. well..back to the drawing board. Idea #493 I figure if I can heat a filament inside a glass cylinder filled with inert gas, I can get a thermionic action and get a process of 'amplification' via anodes and cathodes. I can call this a 'valve'. This may or may not prove useful. mike |

You're about...er...um...54 years late. I bought one, calibrated in frequency, from the RSGB in about 1950. Mike |

BDK I seem to remember Collins used to market a dipole which basically consisted of two tapes which I think were calibrated directly in frequency. Dave |

Dave I wonder how well they held up, I have about a half dozen measuring tapes that have no end on them just from smacking into the case when they closed up. Cheap ones, good ones, they all seemed to break. Why am I keeping them?? Well, I have no idea... An attic antenna?? Hmmm BDK |
