At the moment the repeater is already working at a location in Arnhem (JO21XW) in 40m (120ft) hight. It reaches places in a 30km (18 miles) radius.- Pictures of the present location with antenna, other hardware and the outlook etc. are in preparation.
Then, in a few weeks, we finally hope to find a very free and high place. Negotiations are already going on.- As soon as we know more, we shall show and introduce the exact place more closely to you. Please have a little a patient.
What you see on the left is the present antenna situation for receiving on 1.2 GHz and transmitting on 2.4 GHz. On the top it's the Alford-Slot antenna (1.2 GHz). Right below we use a construction (2.4 GHz) of four dipol-groups (each four elements,- hidden under a water-protection), which are connected together by a 1:4 power-divider. Hereby the radiation pattern can be adapted to the local requirements. We estimate the gain of each antenna to about 7 dBd.
Our latest project for an 2.4 GHz high-gain antenna is a half-sided 11-slot antenna. First measurement results were very satisfying: a gain of more than 13 dBd is more than we could expect. We'll introduce the antenna to you later on...
The green zone represents the border between Germany (on the right) and the Netherlands (on the left). The HF is mainly beamed into the direction of Kleve, which lies in the south-east of the repeaters (marked red on the map) location. The distance between Arnhem and Kleve is about 24 km (15 miles). If you want to look for Arnhem or Kleve on the map, try to locate the river Rhine in Germany and follow it up to the north until the river crosses the German-Dutch border...
