Re: Antenna tuner suggestions / help

Dan Morris - KZ3T

Jeff - Thanks for the info.  Well, two different antennas. I thought about the ground plane but opted for the regulated vertical with tilt over in case of strong winds, etc.  Thanks agn.

Dan  ,,,,, I have the Zero Five 10-40 with ground plane .... I have been happy with it and use it on my IC-7410 for phone work ..... I followed the recommendations and mounted it at 20' .... Tom explained any higher is a waste as the ground plane rods mounted on the base work off  the ground {real ground not electrical ground} ,,,,, I elected to get the model with the ground plane rods as I didn't want to run the radials {too lazy at the time to run em} ..... I have the antenna feed with LMR400 coax tuning it with a MFJ 993b auto tuner and the combination seems to work great ..... I have worked much DX off it when conditions where better.

I have full lenght homebrew dipoles for all bands running all over the place and bought the Zero Five just for a quick scan of the bands on the IC-7410.

As you know Dan the Zero Five is a very well built and designed antenna ..... I gotta give it a 5 star rating.
but I don't know if you would gain that much by going to a longer mast ...... however the more radials the better.

I am comtemplating their 43' model and center mounting it on my 40' x 50' all metal shop and working it off the metal roof instead of running wire radials..... I spoke with Tom at Zero Five and he told me that he has several customers that have done similiar mountings with good results ,,,,, but that project is down the road ....

Dan hope the information helps but every antenna situation is different .... if you look on my QRZ page you will see my rats nest wiring but hey it works for me plus my station is located in my shop and my XYL leaves me alone out there so neatness doesn't matter ... hi hi

Jeff — Which Zero Five vertical do you have?? Just curious as I have the 27’ vertical with 40 radials all at 27’ long.  Seems to do well but don’t know since I have nothing to compare it to.  I have often wondered if I should jump up to the 33’ or the 43’ vertical.  Not sure the 33’ one would make that much difference.  I thought the 27’ would be best for me for operations on 10 meters but hey, 10 meters is just about non existent right now ...

Hi Martin....
I have been using MFJ tuners for years ...... 941D and 949E both manual tuners and still have them and they are at least 25 years old and still work fine .... The only thing I replaced in them is the light bulbs......  I have 2 MFJ 993b auto tuners which I have hooked up to my IC 7200 and IC 7410.... I bought the auto tuners we I got active in PSK and jump around the bands a lot..... I have been very happy with them and I had a problem with one of the 993s during the St. Pat contest but as Jim pointed out all I did was do a reset and I am back in business..... I have a bunch of homebrew dipoles plus a Mosley TA33 and a Zero five vertical {obviously I don't live in a deed restricted neighborhood} and all my MFJ tuners whether auto or manual have been able to tune down to 1.5 or less..... I had a LDG auto tuner but was not happy with it and gave it to a ham buddy down in FL...... I know that most hams either love or hate MFJ but I have no complaints and would buy em again.
Just a footnote  MFJ is about 15 miles from my QTH but I always order or buy from a retailer as MFJ will only sell at the retail price and I can buy their products cheaper from a store or online.
I feel that MFJ gives a lot of bang for the buck .... but maybe that's because I have never had any problems with their products ..... and maybe a little luck of the Irish on my end ?

I'm looking to tap into the knowledge of all of you here a bit.  My main shack is in my house but I have a secondary shack in my garage with a simple Alinco radio and a VHF setup as well.  I'm not specifically planning to do any digital from there but I do most of my antenna design and builds there.  
I'm experimenting with different wire and verticals and am thinking a manual tuner is going to give me more flexibility than an automatic tuner as I also get a little bit more insight (plus I wonder if a manual tuner will allow me to sometimes to a better job than auto tuners).  At the moment I'm sticking to max 100W although I have a dedicated 240V circuit for an amp already installed.  What would you suggest without spending a ton of money.  MFJ (yeah I know their reputation) has like 3 million models and I'm just lost. 
If anyone has a used one laying around that they don't need and am willing to part with as well for some $ I'm open too.
