the Texas Eggbeater II.... Even without a preamp, these are good enough for most LEO satellites.
I am very inerested in performance reports from omni leo antennas, so could you clarify "good enough" for us?
Good question Bob . . I suspected someone would call me on that .. /;^)
I have had these a little over a year now, but have not been following the satellites as much as I'd like to. I have little to compare with, as my last major satellite Ops were AO-13, with multi cross-yagi . . . Now with no steering and less than 30 watts, I'm pleasantly surprised.
With no outside antennae I was not expecting much, and built these for versatility (specifically for the attic). I was impressed tho, and have made contacts via VO-52, FO-29, AO-7 (only tried a few FM, too crowded). Initially I used preamps, as I have 60 feet of 9913. After Field Day I did not re-installed the preamps, and still do quite well. My Hustler co-linear vertical is better on the horizon of course, but these two perform better at mid to higher elevation - less fading than I expected. I do get some pretty deep fades on overhead passes tho.
With the linear birds, the noise floor is low enough, I usually hear myself well. I can't compete for the FM capture in the flying repeaters, but have been doing APRS easily via ISS when it is active.
I guess for me 'good enough' has meant that I'm encouraged enough to continue working with these rather than trying to come up with something better (for omni attic antennae). Someday soon I hope to get moved and get my tower re-planted... (probably will keep these for 'attic-work' tho)
Perhaps in the mean time I can come up with some more meaningful methods to measure the EggbeaterII performance. I guess monitoring a return-link beacon is about the only way to interpret just one antenna at a time. Any suggestions or recommendations welcome.
Thanks /;^)
