make short work of the rivets used in the original assembly.) If two similar TV antennas are available, making a stacked array is a viable option. Or, Long John high-gain Yagis can be constructed if two booms are butted and clamped together. November QST: Recycling TV Antennas for 2-Meter Use - Page 1
Sep 23, 2021 · Satellite carriers may require a second satellite dish antenna for high definition signals as long as all the local HD signals are received on one dish. If you currently have two dishes, your satellite carrier may notify you that you will need to change equipment.
2. Every thing can be worked on from the ground with the aid of a good stepladder. 3. Antennas can be changed with relative ease. (allows you to compare antennas easily ) 4. Less problems in high wind areas. 5. Far more rugged than most commercial satellite rotator systems available. 6. 12 volt operation.
Jan 22, 2017 · My first weather satellite images with a 137 MHz turnstile antenna. Some time ago I got a 137 MHz turnstile antenna from Jørn OZ6TA. We decided to build an automated NOAA weather satellite image receiver using a modern SDR device. He also had an Airspy he wasn’t using and so it became the SDR radio we were going to use for this.
This same antenna could be used for satellite or space communications as well with the addition of an appropriate reflector. The electrical design is a classic crossed-dipole with 75-ohm phasing section. W4RNL has an excellent article on the electrical characteristics of this antenna with schematics and patterns online here.
Feb 05, 2018 · This yagi antenna was based on the K5OE Handitenna and constructed using 4mm aluminium welding rods and 21.5mm PVCu overflow pipe plus a T-piece. All the original element lengths, build details etc. can be obtained from the amsat-uk web-site.
