Re: 3.4G feed horn dimensions ?
Thanks John,
That is just the simple to understand information I needed.
I'll try it with just the open ended can first then.

Re: 3.4G feed horn dimensions ?
Nick,
The standard tin length is good enough - the probe point to the end short of the waveguide ( Tin can) is more important .
No doubt Peter's data will be fine .
The Chaparral flange addition is to

3.4G feed horn dimensions ?
The 9cm's SG-Labs arrived yesterday and I'm cant wait to get going.
I've found on the G3PHO site a "Soup Tin" feed horn.
I've copied it and the SWR is in the green straight away :)
But what length

Re: 3.4G
Hi,
just look for these ANAREN 1H0566-3. They are good for 100W from 2-4GHz.

Re: 3.4G
Stuart, Hi,
I have a few of these for 2.3-2.7GHz, same manufacturer, but I did not think they would handle high power...... up to 70W as the ones you list.
Thanks for the attention

Re: Mere 23cm beacon?
GB3USK is indeed off at the moment, don't panic! It is solar powered. The combination of short days, 8/8 cloud and reduced battery capacity at low temperatures means the months of December and

Re: 3.4G
Could you use one of the surface mount type couplers such as Anaran XC3500M or similar higher power unit.
What would be involved in making a suitable PCB? or am I looking at the wrong item

Re: 3.4G
Indeed, you only have to look at any Ham design combining multiple PA modules to see that! Why reinvent the wheel?
For mine, I calculated the line dimensions and modelled it with QUCS (free

Re: 3.4G
Neil I think you are a little cautious about proper SMA connectors at the 100W level. I and quite a few others use ILAM amps for 13cm EME that run close to 250W through one, and the output microstrip

Hi John,
I shall register ... I always assumed it was the same info as https://www.microwavers.org/maps/23cms.htm as they looked similar.

You can take a look at beaconspot.uk. Plenty of info on all the beacons everywhere. If a beacon has an outage, there is a facility for the beacon-keeper to insert relevant details. It’s

Re: 3.4GHz
Had my transverter for some time. The Post Office tracker never did pick up on it, it just arrived a few days after arriving in the UK. Is anyone else in the South-West coming on 3.4GHz so I can work
