10GHz parts needed
#1
Ok, I've started working on my 10GHz project again, and have a basic personal beacon working on the bench.

[Image: 38957770782_7cb4b00854_z.jpg]

I'm using a ZLPLL programmed to 108.005 MHz, which is x96 by the Kuhne beacon transmitter, up to 10368.480 MHz.  I'm also using an OCXO 10MHz reference, built from a Zl2BKC kit.  For testing I'm using a PCB log periodic antenna.

What I'm looking for now is a real antenna for this project, probably a slot antenna.  Does anyone have one they'd sell to me, or know where to buy one?  I'm aware of the PE1RKI antennas, but I want to see what else is available.  What about PCB patch antennas?  Any hints on how useful they might be and where to source them for 10 GHz?

I'm also looking for WR90 waveguide (flexible and rigid lengths), coax adapters, feeds, a GPSDO, an XRef kit/board for my FT-817, and anything related.

Why don't you put that whole transverter at the focal point of a 60cm satellite/Foxtel dish?

Keep your eye out on council cleanups....

Slot antenna, too hard, go for a horn.
Because, the only frequency dependant part is the coax to waveguide transition.
Give me a call, Penrith area 146.450MHz

I'm using a horn for the xverter, and I needed the slot antenna for a personal beacon (which I'm now building).

I'll give you a call next time I'm up on 2m.

I have some WR75 waveguide bits and dual port feeds 10-15GHz also some bp filters and circulators along with a 3 watt and 8 watt Codan HPA for 14Ghz Ku band uplink tx also some 3 watt NEC HPA's that may be of use to some body all reasonably priced Tom VK4DDG Gold Coast

Hi there James and other readers.
Where are you up to with your 10 GHz project?  After all, it's around six months since your first posting.....
If you're still interested in a slot antenna for that band, I do have one available that is "half omni-directional" in azimuth, meaning that it has its slots only on one side.  This means that it radiates an approximate 180 degrees pattern rather than 360 degrees.  Of course, having a goodly number of slots means that in elevation its positioning (read 'tilt') is quite sharp.
See what you think.....
