Increasing the number of antenna ports in Power Genius

  • 1
  • Question
  • Updated 9 months 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/

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?

Peter were you able to find a DXE Switch that functioned the same way as the AG Switch? (2x8)

" 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....I am sure ithe PG will be a very good amp, but I could not justify the extra cost."

I was on the fence between the 2K-FA and PG-XL as well.  As for price, prior to the PG-XL being introduced I seem to remember the 2K-FA costing approximately $6k or about $1k less than the PG-XL but now there's only a $304 dollar difference, which is trivial considering the price of these amplifiers.

Not having an ATU built into the PG-XL wasn't a concern for me because I own a legal limit+ auto tuner and a self-tuning SteppIR yagi but I do wish the PG-XL had 6 built-in output ports, although external switching options are available.

The biggest drawback I see to the PG-XL (and why I'm occasionally tempted to cancel my PG-XL and order a 2K-FA), is not knowing how long the PG-XL wait time will be.
