Cheap broadband planar elliptical dipole antenna

Cheap broadband planar elliptical dipole antenna. The antenna consists of two ovals (Goldern Ratio) disks Inner of the coax goes to the top disk, Braid of the coax goes to the bottom disk. Each of the ovals dimentions are 335mm x 207mm Short length of RG58 or LMR195 would be ok for connection to the...

Re: Discone Antenna

Hi, I`m planning to post shortly details of an antenna I have developed that you will be able to transmit on (146mhz) and anywhere between 250mhz to 2800mhz with an SWR of around 1.5:1 throughout the range. Will receive 118mhz to 2800mhz or greater. This based on a dipole so it has increasing gain i...

Re: RA0SMS Miniwhip bad performance on SDRPlay

Went back to my original setup for reference ,8mhz and 14mhz dipole (V for 14mhz and inverted V for 8mhz)with 1:1 balun and a MFJ-945D mobile tuner. And this of course allows me to cover all HF freqs very well and not surprisingly better than this mini-whip. Will experiment a little more with my set...

Re: RA0SMS Miniwhip bad performance on SDRPlay

Bought a RA0SMS mini-whip and managed to get it working with my SDRplay v1. At 12v DC its poor and a mass of noise, Though at 4.5v DC it came alive with good to pretty good reception and low NF from around 5mhz to 27mhz. Gain setting was 40 no-LNA for SDRplay with HDSDR. Definitely needed ground lea...

Re: SDRuno C_Band Jaero reception.

I think your accessing L Band (1.5ghz) signals not C Band (3.6ghz). The Norsat 3220 LNB is a for C-Band reception 3.4ghz to 4.2ghz which down coverts the the 3.616mhz signals to the SDRplay. So it can receive/decode them on the 1500mhz band. For interest sake i`ve attached a pic of my modded satelli...

SDRuno C_Band Jaero reception.

SDRuno is working quite well with Jaero C-Band reception. The antenna is 2x 2.4ghz half dish type antennas fixed together and with added flywire mesh glued to the surface. Using a Norsat 3220 LNB and a 900mhz High pass filter for input to the SDRplay. A wider bandwidth for Upper Side Band (SSB) for ...

SDR-Radio/Software/performance

Had my SDRPlay a week and quite impressed so far. Was having problems with SDR-Console changing Freq-Bands. Downloaded the latest version this morning "SDR-RADIO-Pro_v2.3b2274" and it seems to be a vast improvement. Can change bands easily now...e.g 9.7mhz NewZealand radio to UHF without having to s...
