7 elts dk7zb + bigwhell 70cms #qrp #diy

Meet the bra designed just for small boobs that fits like a second skin ☁️ No more cup gaps, awkward padding or digging wires. Just you in all your glory 🔥

Hiker's Yagi: dk7zb ultralight with 3d printed elements.

4m 7ele DK7ZB yagi

Job done.
#DK7ZB 10ele 28ohm for #70cm #AMSAT excersises good to go. Just final touches.
Please do not laugh - this is prototype mount, just to test if fit to ordinary camera tripod.

Homebrew 70cm antenna crossed for sat, inspired by DK7ZB. Band wide 10mhz, centered 432mhz , 1.3 ROS , Z=52U. Personal 3D print supports

Try 1 roll of custom packaging tape for $9.

4el 70cm DK7ZB Yagi is completed! And it even works :) #hamradio

Freshly assembled VHF Yagi, DK7ZB structure, 5,00 m Boom, Gain 12.5 dBd.
VHF DX and EME?

Ready for Es on #50MHz & #144MHz with @DK7ZB 28 Ohms antennas.

DK7ZB Soon on the air for the IARU UHF Contest #uhf #contest #hamradio

The DK7ZB match using 2x 75 Ohm cables

Homebrew cross yagi DK7ZB for sat. Alls supports elements are printed with 3D printer .
ROS 1.2 from 144 to 146mhz

Once again on #144MHz #hamradio contest from JN88ST. Logged 92 QSOs in 3 hours. 100W and 4x5el.DK7ZB and LNA

New singlefeed duoband yagi (design by DK7ZB) is somewhat finished. Still have to fix the plastic mounts and come up with a solution to fix the elements other than by friction fit.
2m resonance point 145MHz, 70cm should be at 435 but actually seems to be at 439MHz so far.

Preparing new remote setup with new bands. IC-9700 +
2x16el DK7ZB 70cm + LNA HA8ET, 36el YU1CF 23cm 25W+LNA LZ5HP at antenna. Still problem with tunning 4x 9 el OWL with folded dipoles for 2m. RAS rotator.

Alex VA3ASE Hi Alex.
Thanks. I love ❤️to build antennas, that's true.
It's 28Ohm DK7ZB design, so need two parallel parts L/4*Vf of semi rigid type EZ-141=FP-75 to get 37,5Ohm transmission line and transform to 50.

Today nice short tropo duct to IN88 with QRB 1500km - only one QSO with F6DBI, but on my side only 50W from my IC7100 and 14el OWL DK7ZB @ 40m AGL

Diy DK7ZB 3-element Yagi antenna, 10M BAND, Set is Good.

6m band propagation is peaking again! Not very often can one work stations like 3B8FA (Mauritius), 3B9FR (Rodriguez Island) and FR4UB (Reunion) from 🇫🇮. All with a compact #DK7ZB tri-band yagi with only 2 elements for 6m!

Upgrade of my temporary #antenna on the balcony from 2el. to 3el. #dk7zb with #3DPrinted parts

New build, 5elm 28 ohm DK7ZB design Will try some meteorscatter #hamradio #antenna #vhf
