This is something that Spike has recommended, so perhaps a
couple of loops at the bottom of the garden well away from the noise-inducing consumer electronics in this row of houses. When I, with the right moral fibre to get something that I wanted, took the Morse test at Portishead (Highbridge) Radio in 1983, and then had a guided tour of the station, the operators had a 32-position rotary switch to select one of many receiving aerials pointed to all corners of the globe. I wonder if these would have been Wullenwebers / Elephant Cages, or somewhere a field of rhombics. What's the recommendation for remote RX antennae, loops or a single whip? |

I wonder if these would have been Wullenwebers / Elephant Cages, or somewhere a field of rhombics. What's the recommendation for remote RX antennae, loops or a single whip? Why a whip? Why not something fully directional? Since you are a pi fan like me have a look on google for a pi controlled direction antenna. Many use old astronomy mounts and while these are actually for telescopes they also work for a well-balanced yagi or similar. My wife is an astronomer and has a number of steerable telescopes I do the building of the computer interface for her. You can pick up old rs232 controlled mounts cheaply on gumtree. https://www.raspberrypi.org/blog/con...d-mathematica/ https://www.mups.co.uk/project/software/astrocat/ There are a number of papers in the IEEE Antenna and Propagation Society library on using a pi to control directional antennas, if you are member of the IEEE or qualifying society then you will have free access.

Actually in Brit, all land is owned by the cancer of the crown and those who think that they are homeowners only hold the property "in fee simple". No entirely correct. This applies under English law only so applies only to England (and probably Wales) and not to the whole of 'Brit'; Scotland and NI have their own legal systems. Scotland abolished all feu duty and feudal tenure (Scottish equivalent of fee). NI used to have a similar system called 'Udal' but that has been abolished. Andy |

Only????? :-) I was thinking in terms of bits from the junk box with additional expenditure of only tuppence ha'penny. But thanks, anyway. Y'er welcome. However all is not lost. If you search for "Antennas made from junk", there are a few that look like they might meet your cost and construction requirements: https://www.google.com/search?q=antennas+made+from+junk Please note that it is not necessary to start with junk in order to produce an antenna that might be declared to be junk. This is not really a bad thing, as it is well known that ugly antennas work best, and that nicely constructed antennas rarely work without the addition of decorative junk. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
