[TowerTalk] LPDA'S and single SS devices amps

[Larry Stowell]

I have to agree with Steve my T-8 is great across the “bands” I started with a C31XR and it was good on 20 and 10 but terrible on 15 very limited bandwidth. I replaced it with a 4L Steppir with the 40m it was a great antenna worked well until Zeus intervened. The only thing was it was heavy and floppy, a lot of torque. I had a new one in hand $3500 (thanks insurance company) looked up at the tower and sold it bought the T-8 $800 half the weight and not floppy works well.    


Rick I disagree with your statement. As a owner of a Tennadyne T-10 and currently a T-12 your statement is flat out wrong. I swept my T-12 with my rig expert AA-230 analyzer and it was below 2-1  across the 13-30 mhz. range. Not sure what you are talking about, OR WHAT BRAND. But to say mediocre SWR is a false statement.

Dick take a look at at  http://expertampsusa.com/ The talk about a new model 1.3K-FA using one device.


I would be curious to see how these LDMOS devices perform. Has
anyone any data on the M2 boxes they sell for 6 and 2 ?

An HF Amp, using one or two of these devices would be very interesting.
