EME Station 2.0 Part 7 – Building Antennas - Our HAM Station
WEBJul 31, 2020 · The next step in our EME project is to assemble the four M2 Antenna Systems 2MXP28 Yagis. These antennas are large, cross-polarized yagis. They feature 28 elements each on 34 1/2 foot booms. The design operates as an independent horizontal and vertical Yagi on a shared boom and each plane have an independent feed point.

WEBJan 12, 2009 · STATION REQUIREMENTS. In short, a station with 1 kw output, a sensitive receiver or external preamplifier, ability to run the JT65A weak signal digital mode, good low loss feedline, and a good single yagi (over 1.5 wavelengths long) is an excellent candidate for successful 6m EME contacts.
WEBEME (Earth-Moon-Earth) Two-way radio communication on VHF and above using the Moon as a passive signal reflector. Commonly referred to as “moonbounce”.
Unlocking the Magic of Small Station EME Moon Bounce
WEBFeb 18, 2024 · Antenna: A high-gain directional antenna, like a Yagi, is essential for focusing your signal towards the Moon. Power Amplifier: Boosting your signal strength is crucial to overcome the path loss. Low Noise Pre-amplifier (LNA): Improving the reception of the weak signals reflected back from the Moon.

WEBJun 9, 2021 · The antenna is tower-mounted at 60’ and controlled in azimuth only. Without being able to track the moon as it rises, the Yagi is broad enough to give me about 2 hours of moon-time on each session before I start to lose signals.

WEBJul 31, 2020 · The next step in our EME project is to assemble the four M2 Antenna Systems 2MXP28 Yagis. The four EME Antennas in our array will have a total of 112 elements! These antennas are large, cross-polarized yagis.
WEBAntennas – A single yagi, horizontally polarized (not circular) with about 12.5 dBd gain (or about 14.6 dBi gain) with an azimuth rotator should be sufficient. Having the ability to elevate the antenna will give a lot more flexibility as to when you can operate along with a lot of moontime.
Why EME with 100W and a single Yagi-Uda antenna is possible?
WEBJan 17, 2020 · A 9-element Yagi has a gain of about 13.4 dBi, so one of these on each end gives an improvement of 26.8 dB. A receive pre-amplifier at the antenna makes the minimum discernable signal of the receiver basically irrelevant. With enough gain, we can bring any signal above the receiver's MDS.

WEBAug 15, 2020 · For the antennae, I would build an array of four 6-element yagis. Each yagi should have a gain of around 9,7dBi, so the whole array should provide around 15,5dBi. 70cm: My rig is able to provide 35W at this frequency. However, I did not find any affordable amplifier for this frequency.
EME Station 2.0 Part 10 – Antennas On The Tower
WEBSep 4, 2020 · The first step was to arrange the four 2MXP28 Yagis that we built on saw horses near our EME Tower and check each antenna’s vertical and horizontal SWR. Performing SWR measurements with the antennas close to the ground like this does not produce very accurate measurements.
