 An overall view of the full antenna system

The HQ will assign a special callsign "Yagi addicted" to all approved requests and it will be the AT President himself, assisted by the event Ideator/VicePresident, to review and approve all the requests.

Important ~ Read carefully: Note that only Yagi  antenna users are accepted to activate during the Yagi100 event and should your application be approved by HQ the pics of your antenna will be displayed in the event's Photo Gallery. Remember that by submitting your application you accept that it may or may not be approved. 

Those who have already sent their application and their photos do not need to resubmit anything!

Band and bandplan: Activity must take place on 11m band. The section of the band between .500 and .600 included (so called DX part) cannot be used for QSO.

e.g = Basic scoring valid for only countries (excluding Japan) with four active "YAGI" stations: Each worked country adds a multiplier + 25 points for every worked station and the bonus of an extra multiplier activates only when the word YAGI is fully completed (25x4=100)

Each worked prefix will be a multiplier. The goal is to do ein plein with QSO on the four stations to complete the word 'YAGI'. Upon completion of the word 'YAGI' (1) multiplier is assigned.

All stations will have the same value = 25 points each.

Even in countries with fewer than 25/30 AT it is possible to have the four stations that make up the word YAGI: for example: 329AT/Y100HQ - 329AT/A100HQ - 329AT/G100HQ - 329AT/I100HQ

In the countries where there will be many candidate stations it may be necessary to do order by making some variant. Our suggestion is to submit all your applications as soon as possible!
