- A standard Slinky coil resonates as a quarter wave between 7 and 8 MHz, when it is stretched to a length between 5 and 15 feet.
- 2 x 6m Slinky dipole appears to be only 20% longer than a same-size wire dipole.
- As with all antennas, operation at a resonance frequency is not required, it only makes matching to a feedline easier.
Conclusion: Not worth it.

A basic grounding rod is an easy and efficient way to protect against an induced current but the correct answer is "take your antenna the fuck down, you idiot" because even if you ground your antenna par excellence a near miss that close to your house can still fry your electronics. Just nigger-rig some sort of pulley system so you can either raise/lower or retract/extend your antenna as needed from the window.

What if I told you there was an easier way to construct antennae?

All you need is a nail in a tree at preferably 2/3rds its height and a wire connected to the nail. Using this setup, in 1904 George Owen Squier picked up distant signals that very few man-made antennas could receive from across the Atlantic. Few believed his claims at first, assuming the wire itself was the real antenna, so he simply insulated the wire from the nail and voila, the signal was lost.

Pictured is a similar setup that doesn't use a nail, possibly more effective.

If we want our hobby to continue in this day and age, we have to realize there are 18-25 year old dudes here who have never tuned an analog radio, let alone ever used the AM Mode in their car radio, so I try to be as helpful as I can and don't mind walking them through the baby steps.

Subtract sum of losses from gain, 1dB remains. Check the option that matches > 200W and < 400W (would be 3dB). Don't waste time with calculations.

>I read the FAQ. I suppose it would be easy to electrocute yourself.
Yes, and in interesting ways. And there are also other dangers like RF dumped into your skin. Happened to me once, not fun.

>I don’t really understand jamming emergency lines though.
It is about harmonics. If you have a transmitter set to 1 MHz, the harmonics will be at 2, 4, 6, 8 ... MHz. You will emit junk there but that does not mean you can also listen to those frequencies.

>Can you really listen into police radios and civilian cellphones?
Yes, but for that a simple SDR is plenty. Most of these are encrypted and you will need some extra stuff to decrypt that which is not trivial. You can at least see that there is traffic and with some effort do traffic analysis.

>What you ever heard anything really interesting or spooky?
Since I used to be a mil spark I guess I have to answer yes.

Get the 2m 70 cm HT and antenna, delete the rest and get a Software Defined Radio like the HackRFOne since you're keen on spending some money and a discone antenna for it.

For an RX antenna, just about any discone or random wire will work. People like the Diamond and Tram ones. Just remember higher is always better.

Coax? The again with a receive only unit, it's not all too important. (Yeah, LMR-400 might loose less signal, but it's not going to be noticeable to an average person).

Should I just grab a UV-5X3 and a good antenna? I'm in FL and it would be used mostly as an emergency/hurricane/SHTF radio. I'm open to suggestions, but I'm leaning to the X3 because it's tri-band and takes all the UV series accessories.

I have a mount point I attached to my house that has about 3 feet of space between the top and bottom clamp, and currently have a 21ft piece of 1 1/2 sch40 in it, but that's far too heavy to double.
Not sure yet how tall I need to go but whats there isn't enough.
Also the only antenna on it is a log periodic, about 2sqft of surface, so meh.

My current plan is to get five 10ft pieces of 2in, cut one into four and slit those down the length so I can slide them on as couplers and just screw it together. something something 40ft stick. If I have to guide it, I have a fren who does a ton of fishing and can probably get me something suitable, like deep sea stainless braid or something.

The best antenna I've ever had on my baoememe was a random sma to bnc female adapter. I stuck a piece of 2 meter solid copper wire in the fitting, climbed on top of my roof with a beer and was able to hit repeaters 30 miles away.

I mean, I already have something like that in the works. I got myself one of KB9VBR's Slim Jims, an antenna mast, and about 20 ft. of coaxial. I just need to get up onto my roof, bolt in the mast, and stick the slim jim up there.

Hey guys!
I'm looking to build my first antenna for a Baofeng and looking for more information. For example what are the advantages of a J Pole compared to a 1/4 wave ground plane? I've looked into antenna calculators but couldn't find any info about the diameter of the copper pipe. Is there a way to tune Antennas without an swr meter? And the final question: Are there any clear cut advantages to 70cm over 2m? With the testing I've done with my friend it seems that 70cm has higher range or is it just because the standard antenna is better suited for it? Tanks a Lot!

Still considering the 5X3 or the F8HP. How much of a difference will the extra 3 watts of output power the F8HP has make? Is it worth sacrificing the third band the 5X3 has?

Also, looking at this image. The 5X3 seems to offer more features over the F8HP. The listing also says the 5X3 has "VOX Talk Around Mode Busy Channel Lock-Out (BCLO) Transmission Time Out Channel Receive Only (TX OFF) Frequency Reverse Squelch Tail Elimination (STE) Work Mode (Selectable VFO/ Menu Lockout)". However the F8HP looks to have a better display.

Do both of these models have these features or just the 5X3?

As for the cable, it's a nightmare. If it kinks, it's kinked for life, connectors that fit it are expensive and it's difficult to feed in general.

I spent like $500 on a cellular repeater with hopes of getting cell service at my house, and I do but cant transmit out for shit. 10kbps, barely sends texts. I need good service to be able to work from home and stuff.
My options are a shortish mast on top of my house which I have now but can make a bit taller, but I need as little loss as possible, a hill behind the house which I can construct a 75ft tower on, but it is roughly 350 feet of cable length and I can only tolerate a loss of 10dbm there.


I'm also looking at kits that convert the rf to fiber and back to RF but I have no idea how any of this works. if that works how I want, i can run it up to a different hill about 1.5 miles away using all fiber and get damn good signal.
idk if I can even use 1 5/8 heliax and see the super low loss at such a tiny transmit power.

To put real numbers in, the FCC lists the device as transmit power of 178mw at 1.71-1.755 GHz which is the transmit band for my phone. currently a center freq of 1727.5mhz.
so I put that in a calculator and it gives this.
I get -109db at that spot without being 75ft up so idk.
I have no idea what I'm doing

Yes I found that a long time ago but I re-read it nd it unfortunately doesnt cover transmit signal and what to do. I have acceptable rx, I get about 3mbps down and it's stable and decent. It isnt the best it could be because the range away from the indoor side is very poor, but it covers the room well enough.

I'm also not sure where to point the antenna or if I should change to a omni/pad because I do not have LOS at all. In fact this could be an additional issue because I just pointed the antenna (log-periodic) towards the closest city.

We already lost part of the band to UPS (220 to 222) and because of that, many people are not investing in radios or repeaters out of fear of having expensive bricks if more of the band is taken.
