Does anybody have a good article from building an Eggbeater for 144 and 435 MHz?
I have built several of these in the past (Eggbeater II by K5OE), and currently have two in the attic - one each for 145 and 435. They serve me well, both for satellites and horizontal-omni for VHF contest. I have no outside antennae currently, but the 144 version I built for my Dad 6 years ago is still intact atop his 50 ft tower. I will probably paint the PVC on the next ones I build for outdoor service.
The original website is gone, but I recently found a mirror site : http://www.observations.biz/K5OE/ look for Eggbeater link. Construction is simple, the given dimensions worked well for me. Hopefully you have or can locate some RG-62 (93 Ohm) for phasing loops. Build the 70cm version first, as the smaller elements are easier to handle. The experience will help in construction of the 2m version.
I currently have no other antennae for comparison, but these are an improvement over simple verticals. I appreciate the fact that they provide horizontal polarization at the horizon - as I also enjoy the VHF contests. Receive preamps are nice if you have them. (no need for a rotator either) On satellite, I use a Yaesu FT-736R (25~30 watts), about 60 feet of good air-dialectric coax for each, and these two Eggbeaters. I typically only operate on VO-52 as I prefer linear modes...
I have been away from the birds for several years, but I am now returning - thanks to these antennae... Good luck, enjoy - and let us know how you progress.
Thanks /;^)

Thanks for the link, the image for the phasing harness is not working.
Do you have the orginal image?

Hummm. I hadn't noticed that that link was to the original site . . . I made a sketch from that, and have taken pictures during construction. I will put together a quick page on my website that has some more detail, and let you know when it is available. (Hopefully sometime this year)..
Thanks /;^)
Dear friend Alan
I built the antenna EGGBEATER II for 70cmt in http://zs1i.org.za/eggbeater%202.html I had it proving during 2 days, regrettably don't listen any station in the AO51 with that antenna. The measures and distances are exactly he says the diagram
With that antenna I have zero gain in RX, I with the ground plane of 70cmt list better.
Wanted them to help me that is which is the cause of the bad reception of the
I will send them picture of the EGGBEATER II that I built.
A million thank you in advance.
Strong hug and very happy and I prosper 2009 for you and family.

I have a 500 ft roll of RG62A/U. AMSAT members can either send a SASE to me, or paypal a small donation to Martha at the AMSAT office, and I will send them plenty for their project.
