 A photo of the antenna

 A photo of the antenna support

 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.

 Scoring:

 Basic scoring valid for only countries (excluding Japan) with four active "Y-A-G-I" 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). 

 Special scoring valid for only Japan's activators (special guest included): 100 (one-hundred) points per QSO with japanese activators (special guests included).

 Each worked country will be a multiplier.

The main goals is to do "ein plein" with QSO on the four stations to complete the word 'Y-A-G-I'. {upon completion of the word 'Y-A-G-I' (1) multiplier is assigned!} and to do QSO with all japanese activators (special guests included).

 Attention: for Japanese activating stations there is NO "ein-plein" for the "Y-A-G-I" stations but an additional multiplier will be obtained after completing four different QSO with the following AT stations: 25AT/YAGI100; 25AT/UDA100; 25AT/TU100; 25AT/YAGI100HQ

{the special guests are separate by it and their value will always be 100 points}

 All stations (excluding Japan) 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! 

 Rankings; Certificate Download and Prize for the first Hunter: Please remember that this is not a contest but it is confirmed that a general ranking will be established by 1AT074 Max. Additionally, a digital participation certificate will be available for download for all hunters.

 The first ranked hunter will receive a 4-element monoband Yagi by Smartech! 

 The 4el Yagi antenna is reserved for the first of the "pure" hunters, meaning that even the activators (e.g. of the multi...) can make some QSO as hunter on their spare time but they cannot compete of course for the antenna up for grabs!

Logs - {but for  Internal Use only, for AT activators only}: Logs must be sent no later than April 15, 2026. Only logs created by ATLOGGER are accepted according to the software instructions. At the end of the YAGI 100Y event, activators are required to send the log via ATLogger’s SEND LOG button. Paper logs or logs created by different software will NOT be accepted. {No logs for hunters}

expired: This rules may be amended at least until the deadline (28/02/2026) for the submission of activator applications.

Hey! Yagi 100 Anniversary is coming and don't forget to check propagation!
