It needs a bit more work, Marc. Fiddle with it some more and send another test.  It doesn't know how to spell "everyone" yet.

Yuk yuk yuk.

We are planning to have the 2021 edition of the Stone Mountain HamFest on November 6 & 7, 2021 at the Gwinnett County Fair Grounds in Lawrenceville, GA.

 

We just wanted to give you a short shout out that the Ticket Booth for the 2021 Stone Mountain HamFest will open on August 1, 2021.  So, on or after that date head on over to the following link:

And be sure to get your tickets early this year.  Those buying their admission tickets via the PayPal link will be eligible for an Early Bird prize drawing.  The actual prize has not been decided on at this time but will be listed on the web page when selected.

 

We look forward to seeing y’all in November!

My comet is only 20 feet up.  I would like to get it up another 15 feet.
What happen to the days you go to the store and get a Channel Master 40 TV antenna mast?
Now you have to have shipped to you.

Many people like the antenna you have, Rodney. I've used one not too different from yours, an R5, and was happy with it. I was in Rhode Island next to a salt marsh. However, it seems to me that since you are thinking of an amplifier you must be somewhat unhappy with its performance. It's your station and your money, I just don't think an amplifier is going to make you happy. Every antenna is a compromise to some degree. I've got fairly decent antennas now, but am unhappy with some aspects of their performance too. There is no doubt in my R5 experienced mind that the people who designed the Comet made some compromises that aren't serving you as well as you would like. 

I've given a presentation of my low band antenna journey to several groups, including one in England. The Deep Dixie Contest Club recorded it. A link is below. It sounds like you don't have the room I do. Fine. The presentation is really about understanding how verticals work and understanding how your choices affect its performance. Maybe you won't find a lot of it interesting. If you don't want to watch the whole thing, but you might find some points interesting in regards to your current situation. Of particular note is minute 42 which shows you might very well have room in your backyard for a 6BTV with radials.
- Minute 20 talks about measured comparisons of a 6BTV vertical to several other verticals. Although the Comet 250b isn’t shown, it is in the same category as a couple radial less verticals that are shown.
- Minute 42 talks about how ground radials do not need to be ¼ wave length long and gives guidance on how many to use.
- Minute 27 talks about how SWR doesn’t mean much in regards to antenna efficiency. It gives an example of how one antenna showing an SWR of 1.4:1 still puts 96 out of 100 watts into the dirt instead of into the air.
- Minute 16 discusses losses in antenna tuners.

I've put that same R5 up when inland away from the ocean. Up at 30 ft like they say. As compared to the better designed antennas I now use it doesn't work very well there either. I did buy another one, but I'll only use it for portable and/or emergency operations now.

Hope that helps to get you thinking.

Carl's suggestion of improving your antena seems a much better route -- whether it is to get a hex beam OR improving your vertical's performance. Especially since a hex beam would give you improvements on both transmit AND receive.

At the risk of stating the obvious... Going from 100 watts to 250 watts is basically a 3 dB improvement in your transmitted signal. That helps, but mostly only if you are chasing weaker signals like the DXers and Contesters do. Many newer rigs have S meter calibrations of 3 dB per S unit. Older rigs have 6 dB per S unit. Your desired amp will only give a 1/2 to 1 S unit increase in signal for the other guy. You won't make a lot more contacts with that little of an increase. Think of how little difference you see when someone calls you with an S5 signal and while they are talking you see the meter "jump" all the way up to S6. It just doesn't make much of a difference. Is that worth the money?  Not for me. And it's my experience from attending dozens of Field Days that most people just skip over those very weak signals where that one S unit improvement would make the difference. They just don't want to make the effort to dig the other station out of the noise. I'm not an FT8 guy, but I doubt it will mean a ton more contacts in that mode either.  You'd likely get much better performance from a Hex due to its directionality. True, a Hex doesn't do 40 or 80 meters, but the high bands are rapidly coming back. If you're looking at 40/80 then I would focus more on better low band antennas. In fact, that is the route I took here at my own station. By improving my 40/80/160 meter antennas I've seen a dramatic improvement in my ability to work stations -- without buying an amplifier.

Re: HF Amplifier

Dave Kjellquist, WB5NHL
 

Rodney;

Are you still using the Comet CHA-250B    Carl and Kevan are absolutely right as to where to spent your efforts.  An antenna other than the CHA-250B aka "antenna dummy load" would do wonders.  Even Comet, in there advertise, recognizes the CHA as mostly a radiating dummy load.

"Yes, some of the RF that enters the power feeding section is turned into heat rather than transmitted as RF, but that is one of the compromises needed to create a broad-band, low SWR, multi-band HF antenna with minimal visual impact."


The way they are able to create a broadband vertical is with a lossy transformer. In their "matching transformer" a very wide range impedance on the secondary is NOT accurately transformed to the primary thus maintaining the 50 ohm load.

One possible solution would be a Hustler 6BTV vertical. At Schofield middle school for SCR we used a Huster 6BTV with good success. Even with a very modest temporary ground system it did well. As a single aluminum pole the visual impact is minimal.  If necessary the Hustler can tilt mounted to hide it when not operating.  DX Engineering sells the 6BTV for $242.
