Antenna High !

#105121

Post by newboy »

Hello to all,
I am current have IMAX 2000 Base Antenna on top of 30 feets push up post.I just bought the Telescoping Mast with 50 feets high.I would like to know if it will be increase better for my DX and RX with 20 feet higher or i need to buy the better antenna as MACO V5000 ?.
Thank you for all the helps,

Welcome newboy. One of the sayings is height is might. Having your Imax 20 feet higher won't hurt and could only be a benefit. Try it at 50 feet for awhile before spending more money on a different antenna.

you should see a noticeable difference for the better,not huge though . i think the 5000 is a better antenna but if you already have the 2000 i feel its mostly a lateral move for the money . id keep the 30 feet of pipe and if you really want a better antenna after bumping up to 50 feet id save and get a small beam and rotor . put that on the 50 foot and drop the 2000 back to the 30 foot . use the 200 for local and the bean for long distance . opinions are like elbows.....every ones got a few . that's mine .

Thanks Crazytruker and Bootymonster for your oppion.I asked the sell of the Telescoping Mast for mounting the antenna Beam.He said it is not strong enough to use with any beams.That is why i am thinking of Maco V5000 antenna.
Do you know any smaller beam that will work with 50 feet Telescoping Mast ?.I will keep the Imax 2000 on the 30 feet post to use it for local .It is very hard to talk it down.The Imax 2000 works well for talk in town.I need the Antenna for DX.

hi newboy, yes i agree with the other guys it will help. a cb wavelength is around 36 feet long, having it lower wont allow the first radio wave to form without interference from the ground. also, the higher the vertical antenna, the less dependant it is on the grounding system or radials. the ground plane kits they sell are not even a 1/4 wave long, so they are not too efficient for the money. i think you should try to get it to 40 feet. if you talk to locals, write down what they are giving you on the cb meter before switching antennas so you can notice improvement. beams: even a small 3 element beam will help you greatly in skipland over the antron. for instance, someone giving me a 3 with the antron will give me a 7-8 on the meter with the beam. thats as big as you could go with normal tv mast and tv rotor. other wise you would need a tower for anything larger. i wouldent trust a 3 element beam on pushup poles unless its guyed at every joint! be carefull, and have fun. 209

Thank you 209 first class,
I also think the telecoping mast will not hold the 3 element beams,therefore i have to live with the Imax 2000 for now.

newboy,
I have a cheap 30' mast with a m103 3 element beam with an imax 2000 on top or now I have a dual band vhf/uhf vertical on top of it. I use a rat shack tv rotor and have it guyed ad have had no problems now for 2 years.

Thank you for your help.I am thinking about Maco three Beams,but i am not sure until i read your post.My question is if the Maco three beams under the Imax 2000,will it cause the SWR TO GO UP ??.How do you mount the Rotor on the same post ?.I am very new in CB radio.I hope i can see how it was mounting on the same post .
I will try to read if i can see one.
Thanks,good night.

I notice a significant differance everytime I go higher with my tower. Right now the bottom of the Imax is sitting around 50 ft, and I can hear better than anyone around with a verticle. I also debated the the IMax and 5000 deal. 3 years ago when I wanted to setup a base, everyone said go with the 5000. I held off, and 2 years ago everyone said the Imax, so I did the Imax. Now, 2 years later everyone is again saying the 5000. I would be willing to bet, there are zero differances in performance other than resonating bleed over. Everyone here, since I setup my Imax, has switched to an Imax. I don't know if the word is spreading, or if my setup just sounds good. But if it's not broke, then save the money and use what you've got. I'd invest in tower height, or pole height before I'd invest in replacing a good functioning antenna.

Thanks Linx,
Right now the Imax 2000 is at the top of 30 feet pole.I bought the new Telescope push up pole 50 feet.I will try to get it up higher to see any differents.I have read the Beam antenna is better for DX ,but i don't know if it is true.If i install the Beam than i need antenna rotor. How much is the big different ? I am new to CB Land !!!.

hi guys, i wasnt knocking push up poles, its hard to tell without seeing it. some are sturdier than others. i agree with moonshiner, the 2 antennas are probably very close in performance. moonshiner, have you noticed alot of difference between the beam and the vertical? have you noticed any numbers ? far away signals like a 3 on my meter go up to a 7-8 on the meter with the beam. just curious what anyone else is getting. 209

Thanks 209 first class.
Can i mount the second antenna beams close to the Imax 2000 push up pole ? Will it cause the SWR goes up ?

Try the feed point at about 50ft that Imax should be good to if you want to get a better antenna plane on spending $150 to $200

the biggest difference between the 2 is while I have dx conditions. most of the time there is a solid 5 sunits difference, but not all the time. Polarity changes and times the imax picks up the signal a little better than the beam.

Locally everyone runs vertical so there is a great deal of differnce between the vertical imax and horizontal beam.
