This has worked for me, use a 100' of RG 8 or RG213 I use a pushup pole that was made out of EMT tubing from Home Depot, my A99 is 36'+ to the bottom make a choke using about 7 to 8 coils of the coax using 21' of the coax and tie the choke off close to the antenna as practical, I have no...

Zerofive Antennas Waverider, Have a 43' vertical that I will use over my ground field for 60-75-80 an 160m that was built up from the standard Zerofive 43' vertical setup, Its a Barn Burner on 160m according to the guys I talked to with it on 160m in N.M, AZ, NV and CA after some changes...

Zerofive Antennas BM, You may have done some homework on this one BM, an read the installation sheet from Zerofive for the 10-40m Goundplane, the 100' of coax is the starting point for coax on the project! The antenna will be set at 18' to its bottom. Reference antenna is a Cushcraft R8...

Zerofive Antennas Generally speaking all good antenna systems have be optimized to get the results wanted, an compared to a reference antenna to make sure you get the results wanted. Your criteria for an antenna will always be somewhat different than others because of environment differences...

Zerofive Antennas Most of the ZEROFIVE ANTENNAS are non resonant vertical antenna that work well for DX, first of all being non resonant they don't bring in extraneous band noise, you get a lot better signal to noise radio in less than ideal radio conditions, (you can hear the other stations...

Little Wil Sounds like its Hit or Miss with these antennas hmmm!.....Oldtimer

A99 First things First, Fire-stick makes an antenna for a A99 they say helps make the A99 better, don't know if it does because I have not used one! but what I do know is a A99 has a lot of gain if installed at 36' to the bottom an works well at that height. Back in the day when Big Sticks...

little wilson Had 2 LW about 4 years ago, found that they will not take any power, and if you try using power SWR will be very high, you can try and cut the stinger and little if you SWR on ch 20 is high it may drop it a little hope so. I brought a K30 to replace the Little Wil and it worked a...

I -10K Marconi, I know your right! I publish my finding so others and myself have the finding on the internet while there fresh in my mind, I just publish the finding, not what I think they should be, then if I forget then an often do, I sometimes read them at a later date and it helps me...

I -10K Have had a new IMAX up for 2 weeks now, been using it on 10-11-12-15-17 meters, it works well but my A99 smokes it on all bands in direct comparison by 2S units on my ICOM 7600. so today am going o get out my I-10k and get read to change them out, why am I doing so, my I-10k will be used...

Had a 2547 before with the old power supply worked great, just ordered a new one with the switching power supply, I talk to a friend about 30 miles away that talks on a 2000 GTL barefoot so am going to take on more stab at trying to pull them in just a little stronger with this...

A99 BM, Your first question, the answer is YES. When using the HGP 500 my lowest SWR was 1.2 on 27.205 which would work out to around 54-55 ohms I believe, good but no cigar! I like the HGP very much, but it is not a very wide banded antenna. If I spend some time with this antenna I am sure...

A99 I go along with what the other guys said, have my A99 at 38' to the bottom and it works well no TVI. I just used the antenna as it came out of the box, used 100' of 9913 coax on my roof in the center of my lot. I use the antenna on 10-11-12 an 15 meters works great, did put up a Hy-Gain...

2999 mod I just got through doing this mod to my Galaxy 94HP yesterday, in this case I did a complete alignment to get the desired results, the mod worked well on the 94HP, did a side by side check before and after test against a Galaxy 98VHP an a General Lee which uses a 3600-15c board an is...

Grant Jackson? Back in the day had both, the Grants had duel finales the Jackson's had one big final, both good radios but the Jackson would hear a little farther on SSB and the Grant would do a little better on AM, both neat radios, I once talked 155 miles ground wave SSB on my Jackson, was...

HGP-500 Marconi, When I had the antenna set at 22' I think low SWR was was around 26.400+ as I remember. The antenna was 16' off the ground and I was using a 3' jumper! I don't remember what the reactance was, sorry. 2 to 1 swr would be about 80 channels I would think, nothing like a A99 that...

HGP-500 Marconi, I built the antenna per the instruction manual which called for 8'9" per radial the only change I made that was different was the overall height was listed at 19' that would be for 10 meters of course. I set it to 22' then I dropped it to where the SWR using my MFJ-259A was...

HGP-500 After installing the new HGP-500 antenna at my QTH last month and doing some primary testing against my reference A99 at 38' to the bottom of the A99 The new HGP-500 has stopped my desire to compare any more base antennas! These are observations that jump out at me so far. The A99...

AMPs Hammer, The KL203 will run on less but a 15 amp regulated power supply would be my choice. A Cobra 148GTL will use 3 amps an that leaves 12 amps for the KL203 an there a little lead way left, so the power supply does not dip on you when it get warm.................Oldtimer

car in truck antennas Antennas are like a woman if she turns you on, she the right one for YOU! At this time in my life a Wilson 5000 hard mounted on the roof of my RAV-4 works good, but is it the best NO, but it does the job well for my needs. SS antennas work well for AM use and copper wire...
