I0JXX 432 MHz Yagi antennas

Technical description

Like all antennas from I0JXX, these 70cm Yagis are characterized by an excellent quality of workmanship and the use of high-quality materials in conjunction with a sophisticated design. The reliability and durability achieved in this way is particularly appreciated by many radio amateurs.

Especially worth mentioning: The assembly instructions for each antenna are clearly laid out, abundantly illustrated and multilingual (English, German, French, Italian). Thus, assembly and installation can be done in a short time.

The coaxial feeding is done via an N-socket at the feeding point of the dipole element with T-match. The balun is made of RG-142 coaxial cable and can be loaded with a transmit power of up to 1000 watts.

If, due to the size of an I0JXX antenna, additional guy material is required to stabilize the boom, this is generally included and does not need to be purchased separately.

Application description

The 432 Mhz monoband yagis from I0JXX are available in four different versions and can therefore be used for many applications.

16JXX70:

Quite compact antenna with 16 elements on a 3.10 meter short, three-part boom. Since this model does not need to be guyed, the 16JXX70 can be mounted at the top of the mast for optimum performance.

25JXX70:

This 5.50 m long Yagi has 25 elements. The boom is guyed, and the necessary material is of course included.

32JXX70:

Are you looking for an antenna for EME or SAT operation? Then you should take a closer look at this cross yagi with 2 x 16 elements, 2 separate connectors and three-part, 3.15 m short boom.

39JXX70:

The longest of the 432 MHz Yagis measures 9.40 m. This means that it is no longer necessarily suitable for the roof of a row house, but it offers enough space for 39 elements. Mounted on a free-standing mast/tower, nothing stands in the way of the "Weak Signal DX". For transport, the guyed boom can be disassembled into 6 parts with a maximum length of 142 cm.
