Martin, my FSJ-4-50 has always been the solid inner type, never seen a braided inner version. Virus-free. www.avg.com

Hi Dave Its about 0.75dB per m for FSJ1-50 I have use the cable extensively for 3cm portable systems too. Its only rated at 100W so I will not be able to run the BIG twt terrestrially, none of the coa

Using LDF4-50 at 10GHz is possible but not reliable. Its fine at 6cm but at 3cm it can support waveguide modes and given the opportunity it will try. If the run is very straight with only very shallow

Julian A 6:1 VSWR is about 3dB Return Loss. Think of it of this way, if your feeder has 1.5dB loss (not unreasonable) and you had no antenna at all, just an open cct, you would get 3dB Return Loss (fe

Maarten the smaller filters do not go down to 600MHz.. 730MHz min Now we are outside the EU, I'm not sure how EU would treat incoming gifts or low value items, The UK has adopted new systems already,

Hi Maarten I have some interdigital filters that will tune easily but they are not very small 170 x 90 x 25. The SMA connections will make the 90mm dimension larger. passbannd is about 10MHz also some

Sorry I forgot to say the manual is for the T30 flavour, but most info including pinout should be the same Virus-free. www.avg.com

see below Full manual available 1.4Mb so i wont attach it here Virus-free. www.avg.com

I haven't looked yet for WG15, I probably have some short bits I have reasonable amounts of WG14 though, if anyone wants some. Mark GM4ISM Virus-free. www.avg.com

My thoughts on power combiners and splitters A technique that might work for you would be to make a Gysel or Wilkinson with Stripline. The Gysel is slightly more complex but has the advantage of emplo

you could always add a 90 deg phase shifter in one leg. The lumped component solution to this wont be as wideband as purists may like but should work fine.. 3 extra components, a Pi Low pass network w

Ive seen similar in Outside Broadcast vehicles in the past. I think Cardiff may have had uplink capability from the Studio, Glasgow did if i recall These are typically 300W+ satellite uplinks operatio

Hi Roger Have you tried hitting the Pasolink multiplier with 23.5GHz, x2? I'm hoping for maybe a little more than the 15mW for the CSB Beacon. I have some 100mW 23GHz Power amps from old Siae links, t

Hi Mike, I'll be looking for it, I would expect to hear it on RS at the 2W level, possibly not at 20mW. Path looks excellent, only 236dB troposcatter loss. You may be able to hear me on troposcatter o

Hi All I can be QRV on and off this evening if anyone wants to test please let me know Zello or KST David, you are quite close, what's your take of like 315 ETN? and your 8 fig loc? Mark GM4ISM IO85AR

Hi Paul Long time no speak. Warwick Uni was a long time ago Much to catch up on. Still living in GM, still playing radio, MF, 6m and up to literally light as time permits but grandchildren keep Serena

Looking at the galvanic potential of different metals, silver vs aluminium actually has a higher differential than stainless steel and aluminium. I don't know of many examples of this combination in p

Mike Stainless steel onto Aluminium is probably worse! Any dissimilar metals will exhibit electrolytic corrosion over time. One solution is to coat the mating surfaces in a corrosion inhibiting compou
