Many thanks everyone for your suggestions and advice.
Venkata – Thanks for suggesting vertical antenna. I will certainly consider it.
My concern regarding verticals is the footprint required to accommodate
sufficient length of radials. Your thoughts are welcome.
Rudy – Unfortunately, I won’t be able to accommodate the longer wire length
(~132 ft) required to go up to 80m in my backyard. So, a loading coil is
probably the only option for me.
Anthony – Many thanks for suggesting building it myself. I have decided to do
just that. I will reach out to you for help.
David M. – Many thanks for suggesting NanoVNA-H4 antenna analyzer. It is good
to hear it works well for you. Anthony thought it was a good choice as well.
David K. – It is great to hear EFHW antenna is working out well for you. I
plan to build one. Running it along roof ridge vent is a great idea. I will
think about how I can accommodate that.
Jeff – I greatly appreciate the YouTube link. It is very useful.
I am planning to be at the next BVARC POTA event at Galveston
Island State Park later this month. Since I don’t have a HF rig yet, POTA will
be a good opportunity to try out my antenna if I can build it before the event.

Subject: Re: [BVARC] EFHW?
I have an EFHW with a 49: 1 balumn (transformer) that is cut to 40 meters that
I bought at the Houston Hamfest last March. Along with a Icom 718. Just like
you, we have an HOA management that will not allow antennas. So I ran it along
the roof ridge vent. Very stealthy and you can only see maybe 6”where the wire
comes out of the roof.
It works on 40, 20, 15 and 10 very well. With an analyzer I can get 80 and 17.
12 not so much. Was set up in April and have made a ton of contacts
I am planning on building one for a portable operation when I am traveling.
If you can build it yourself Do so. There is not a lot of materials and it
doesn’t cost a lot.
Good Luck

The Nano VNA is a great analyzer. I recommend it. It will help you with any
antenna you wish to buy or build. Again building it would be better. I can help
you source most of the parts localy.

I agree with Anthony about building it yourself. I have built a couple from
parts and I prefer them over the kits that I have built.
With regard to the antenna analyzer, this is what I am using and it is fine for
my needs - https://amzn.to/46A5mYk I would encourage you to watch some YouTube
videos on how to calibrate it prior to use.

I know you are being told the buying the ARRL EFHW is a good idea, but as one
that has built many EFHW antennas. I would recommend building it. It is cheaper
and most parts can be sourced in town. If you have any questions or need help
doing so let me know.

I have built the ARRL EFHW kit. It works fine. The kit come with wire to
make to work for 10-40 meters. You can get a longer wire and it will work
for 10-80 meters.
That said MOST HOA rules state you can dow what ever in your back yard as long
as it cant be seen from the front street. So with that I would suggest one of
the DX Commander antenna's. You can set these up in the back yerd and odds
are you wont see it from the street..

Hi everyone,
Like many hams, I live in a HOA restricted subdivision, so a
permanent HF antenna is not practical. I have been thinking for a while about
EFHW as a temporary antenna which I can set up and take down quickly. My
question has probably been asked many times so please forgive this relatively
new member for asking again. The question is do you use an EFHW antenna and is
it a good solution for HOA limited subdivisions?
ARRL sells EFHW antenna kit for $80. It is cheap and certainly seems like it
will be fun to build. It works up to 40m, but I suppose it will be possible to
extend it to 80m with a loading coil. I am considering MFJ-1910 33-ft
telescoping fiberglass mast with the antenna. As I like more choices, can
anyone suggest other options/alternatives for the mast?
Also, any suggestions for a good and reasonably priced (< $400) antenna
analyzer?
Thanks,
Amal – KT5AC
