Increasing the number of antenna ports in Power Genius

  • 1
  • Question
  • Updated 1 month ago
PG has only two antenna ports which is rather disappointing for an amplifier in this price range.
Due to a high cost, I do not plan to buy an Antenna Genius and look for other options, considering:
> Hardware cost noticeably lower than an Antenna Genius
> Tight integration with Flex 6000 series and a Power Genius including optional ATU

Can someone offer some practical solutions?
I expect that this topic may be of interest to other future users of PG.

If you had ordered last year you would get the free tuner genius or antenna genius. Tuner genius will have multiple ports. I think 3 if I am not mistaken.

While I wish it had three antenna ports, I believe Tuner Genius will only have two.

It is great that the tuner now has three outputs!  I didn't receive the newsletter so I was unaware of the change.   My info was based on an email exchange I had with Flex back in late May 2017.

Yep, some things have changed. I am beta testing the amp. That said, this is public info...

Thank you for your clarification, Ria. Yes, I ordered the PG last year and three antenna outputs most likely will be sufficient for me.

Just to clarify, it looks like Rita said the tuner genius has three ports not the power genius. Am I correct?

I replied to KF4HR indicating how the PG XL works. Again .... think of it as two separate amps. a side to one radio (or first SCU) and B side to second radio (or second SCU) simultaneously.

As Ria stated, you can only transmit on one band at a time.

OK Dave got it.  Yep no single amp could xmit on two different antennas, bands simultaneously, well maybe one day eh?  I think you have the amp, and I think our posts were near simultaneous in posting.  I see two different radios ICOM and 6700 so that's pretty clear its receiving at the same time as xmit.

Would be nice if the thing ships soon!
Thanks again all, these forums are a wealth of bright folks and data.

I have had the amp since November, about the same time Dave got it (maybe a day after).

I run SO2R in contests with it. To simplify matters - it’s like having two amps where they are interlocked so only one transmits at a time.

As far as spacing goes, I have between 200-300 feet between antennas but some of my antennas are less than 100ft away. I do use the 5B4AGN filter sets to clean up the transmit signal.

Operating at the same time on any combo of two bands of 160, 80,40, 20, 10 needs that extra filtering, particularly during transmit between exciter and amp. Receive filters like what the 6600 (and 6700 to a lesser degree) have are only half of the story. You want to suppress the harmonics before they get amplified. That said PGXL does a great job already. You can even use stubs for a cheap yet effective solution.

When running contests I’m usually on 40+80, 80+ 160, 40+160 or 20+15 (and when 10 opens, 20+10). During the day I always try to keep a radio on 20.

20+15 can run pretty much without external filters. The rest it gets iffy.

‘Ria thanks that’s very helpful. Did you get your amp back yet after the recent mods? If so has it continued to run well?

Unfortunately details of testing are under NDA. You can ask sales any questions about the amp. But I cannot say anything further.

No. It’s a disaster. They short to ground when communication is lost. Mine fried itself yesterday.

So the antenna genius put all antennas to ground if communication lost or power lost to this unit, that is the 12 volts?

Sure.  When it becomes available, add the 8x2 4o3A Antenna Switcher: http://www.4o3a.com/products/antenna-switchers/6x2-antenna-switcher/

Isolation wasn’t the issue. The 8x2 had a LAN connection and RFI caused it to drop comm during transmission and fried the A port despite ferrite beads

I had PG amp on order, but no matter how I did it, I could not justify the extra cost to achieve what needs I have. So canceled. Even with a free tuner there were extra cost. I am interested in efficiency of operation. My station is a lot like the cockpit of a modern jet. In order to keep my objective realistic, my solution was the Expert 2K-FA. Built in tuner and six port antenna switch. I know what your going to say, what about that extra power on rtty, or FT8? Not enough difference to make a difference in non contest conditions. I don’t do contests. Don’t need continuous 1.5k. The 2K was less expensive and included a very good tuner and six very versatile ports. So in a nut shell cost and a tuner (vapor ware at this point) was the straw that broke the camels back. I am sure ithe PG will be a very good amp, but I could not justify the extra cost.

They will sell a tone of them to stations that demand highest performance no holds bared. For the average guy, that is a lot of amp.

Hi Bill, could you define “they” as it would help me understand your post. Thanks... Pat

I'm guessing he meant "a ton" - not tone. 'They' meaning FlexRadio?
