@abcd567, I've read the majority of your posts on this forum and on others, and I linked them in the post, because I've learned a lot from your experiements and simulations on Franklins.
We're on the same page, and your contribution for discovering the cantenna is immeasurable.
Right now, I'm looking at minimising equipment cost, because the ultimate goal for me is getting the best performance for minimum money.
If you can test or simulate a drinks can cantenna (I call it Coketenna as it's easier to understand around the world, Coca-Cola is the 2nd best known world after OK) drinks cans are uniform around the world, 65 mm in europe, 68mm for 12 oz cans in N America as per my research) with various diameter tops and bottoms.
I ran a real life testing with a full-body Coketenna (bottom cut off) and it was worse than a 68.8 mm body, also, indoor tester had worse performance than me, so it's a gray area.
I ran a Coketenna with Pro Stick Plus and had less Totals vs FA plus Uputronics plus v.3, unsurprising.
I also ran 1/2 receiving elemwnt with 1/2 body, dismal.
I do not have the technical knowledge nor time with 4NEC2 to simulate, I'm also suspicious that longer braid off coax cable adds capacitance acting as ground to antenna.
Frankly, I have no clue why Coketenna works so well, so the next step is figuring out why, aldoir suggested that my location influences results, but I'm living here for years and tested ADS-B antennas in three continents.
Right now, I can't change my setup, so want to know how to improve, then if a theretical suggestion works out, I'll go to a hilltop and test again.
I just love antenna testing, like you, the joy
Thanks for helping, I appreciate any words from gurus!!!
I'm lucky as a poor tester that I can test antennas with the best equipment available, and I couldn't look in the mirror if I didn't do my very best to test every scenario.
So please, let me know. Thanks.
