I've been searching for my next 11m antenna build. I ran across the qhf antenna they use for noaa weather receiving and im wonder if a person could build one for the 11m frequency. Would it be worth building or will it preform similar to a 1/4 wave vertical. Not exactly sure of the science...
So I've got my hands on a pair of skip shooter antennas and the swr readings I had at first were 9:1 across all channels. I replaced the coax and now im getting a reading of 2.5:1 on ch1 3.5:1 on ch 20 and 4:1 on ch 40 I have the nails pushed as low as they'll go so shortening the antenna...
Ran across a 30 year old tower that is priced right imo. Comes with a beam, what I'm wondering is what to look for, is it worth refinishing and putting back up? Any pointers would be greatly appreciated!
Thank you

I have an opportunity to buy one of these amplifiers just wanted to know if it's worth getting and restoring. Thinking about running my President Madison behind it or cobra 2000. Any information is greatly appreciated as always

I'm currently planing out making a cubex quad for cb use. I wanted to see if anyone else has made one and if there are any issues I can avoid. Just a young man trying to learn from the more experienced. Any info on the cubex quad or pictures would be greatly appreciated as always!

Thanks as always

I finally got my hands on a pair of skip shooters and got them on the truck after about 2 hrs of messing with them back and forth ive found myself here to see who knows where I'm messing up. The swr reading on ch1 and ch 40 are a 9 which doesn't give me alot to go off of as far as adding...
I've been enlightened and turned onto some different coax. The gage size of recommend 50ohm coax is 15 awg but when looking for 75ohm the closest I can find is 20 awg
I'm wanting to pair my bearcat 980ssb with a 2x4 and phase a pair of skip shooters any thoughts
I've been tossing around the idea of buying a rci 2970n4 and gutting the amp.
Instead of the Mosfets I'd really like to replace the entire thing with a 2 or 4 pill ldmos amplifier.
Is the squeeze worth the juice?
I recently found this at a local thrift shop
Has anyone read through it? From what I've seen it has alot of good information on specific things such as resistors and even goes into amp building. Is there a better source of information available?
Am I getting over my head in information?
Watched an interesting video about coax jumper lengths ect. Now before everyone gets wild and starts picking sides my main question is what equation is used to figure coax length. I'm in the process of turning current system on my cb in the semi from a single to dual antenna and i want to figure...
I'm currently planning on cophasing my semi trucks antennas I've got the mounts, antennas and radio now its time to build a harness. I've been thumming around the internet trying to figure out what coax to use to get the best proformace. Now I know that since the run is so short loss isn't going...
I've been wanting to set up a co phased system in my semi to get a little bit more gain up and down the road. Truck stops do have cb wizards and co phased rg 58 coax which I'm not a huge fan of. My question is what coax can I use, does it matter? Can I use 2 equal lengths of rg8x to a short...
If 11m is basically line of sight, and the fcc says a cb antenna can't be any higher than 60ft. Or 20 ft above the building or tree in which its mounted If i had an 80ft tall tree am I restricted to 60ft or would I be allowed 20 ft above tree?
The reason I'm asking this question is for a...
Hello yall! Just wanted yo see who if anyone on here is from Arkansas or Southern Missouri that run an 11m rig. Ive been on and off for about a month now and uve found a few guys locally on ch37 usb.
Anyways if you're in the north central Arkansas south central Missouri area drop a handle and...
I recently came across a nice kenwood ts-520s. What is the best antenna to get for this radio? Do they have a single multi band antenna that works better or the same as each band having its own antenna? Any input on the best way to set this radio up is greatly appreciated
just picked up this midland 77-882 cb it powers up fine but when hooked up to mic it makes a buzzing sound i felt around and there is alot of vibration coming from the ETA66 not sure what it is or how to fix the radio thougjt this might be a good one to try to get back on the air hook it up yo...
So I've been hunting a power supply for my galaxy dx98vhp which by the manufacturers specs has 10-50w am 200w usb/lsb current drain 25 amps am 40amps ssb and takes 13.8v input voltage
With the given formula
watts÷volts=amps
Am I assuming correctly that I only need
At minimum a 15a power...
so I've made the decision to get licensed so I can play radio outside of the 11m band as "fun" as its been im ready to make real contacts on 20 or 40m all in due time that is.
What reading material would you guy recommend?
Tips for a new tech?
Is there one book I can buy that has all three...
