Comparison of performance 21cm Yagi vs Ptarmigan array for hydrogen line observation
Data collected using ezRA suite and analysed with same software. Link below to PDF of Ted Cline’s analysis of the results. Andy https://www.astronomy.me.uk/wp-content/uploads/2024/09/Ted_Cline_comparison_AP21YAGIPharmigan_020924.pdf
Comparing Ptarmigan and 21cm Plate Yagi data at LRO, collected over few days 26-31/8/2024 – processing both data sets in ezRA
I used ezRA software suite to process the data set presented in the post: https://www.astronomy.me.uk/comparing-pharmigan-and-21cm-plate-yagi-data-at-lro-collected-over-few-days-26-31-8-2024 Both aerials pointed 163 degrees Azimuth at LRO. Ptarmigan Array = 77 degrees elevation. Plate…
Comparing Ptarmigan and 21cm Plate Yagi data at LRO, collected over few days 26-31/8/2024 – the data set
Dear Ted, I have been collecting Ptarmigan Array and Alex Pettit 21cm Plate Yagi data at similar elevation and same azimuth over last few days whilst we have been away.…
Results of shootout between Alex Pettit 21cm Yagi and Ptarmigan ex-military array (band 3)
Nooelec H1 LNA on both Recorded similar time period in few days up to 25/8/2024. ezRA software – ezCol for collection and exCon/ezGal/etc. for analysis and plotting results. Lichfield, England…
Results of first full drift scan of sky with Alex Pettit 21cm Patch Yagi Antenna from LRO.
Data collected and processed in ezRA suite. The graph below can be seen to peak when crosses Milky Way x2 in day. 3rd peak in middle = is this when…
First Light Data Process with Alex Pettit 21cm Plate Yagi @ LRO 22/9/2024
This involved only a few hours of data collection at one elevation, and was done to demonstrate that hydrogen was picked up – appears to peak over galaxy and suggestion…
Alex Pettit Plate Yagi vs Ptarmigan Array for mapping Milky Way at LRO
I have set up the new aerial from Alex Pettit at SARA next to my existing Ptarmigan ex-military dipole array, to see which is able to get better hydrogen signal…
Assembling Alex Pettit’s Hydrogen Line Yagi antenna
Loosely assembled – I’ve asked Alex some questions before I complete assembly. Andy Hi Alex Before I get the old soldering iron out can I check couple things with you:…
